If your linux setup don't have libgluezilla, last version won't work with Mono.
If you have a debian based distro, sudo apt-get install libmono-webbrowser4.0-cil should work for you.
Unfortunately, my distro don't have this library in its repos.
Andrey, is this required by sign-in process?

PS: Nevermind, I have downloaded debian package and replaced corresponding libraries on my system with files in it.

Same question as fedeghi.
In addition, this feels like your moving to a rev 1.0. I've seen multiple requests for documentation. How can we (community) help? gurro recently started the "New series of YouTube videos for learning how to use SMath Studio"

I think you need to turn Exclude Beta versions checkbox off in Extensions Manager to see this update.

Tried logging in, but nothing happened. Is that SMath account a different account than the SMath Forum account? I did confirm that I had the right password for the forum account and tried again, but no success.
Also, the problems I reported before about unwanted math regions being inserted automatically in text regions is still present. I can't enter a date in any common format without it being interpreted as an equation. Using dashes like 01-01-2021 isn't too different on the formatting (more space), but slashes are also common and 1/1/2021 gets interpreted as a fraction, which is an issue. My only workaround so far has been to add spaces and then backspace them out after I've typed everything, which is not an ideal workflow. But it may also be affecting my dropdown boxes as well now. In the screenshot below, the last entry for 3/4 was entered after the update this morning, and it doesn't display correctly in the subsequent dropdown combobox. It still picks the correct value, but the display in the list could be difficult to interpret like this.
Thanks,
Jason

There's also another issue that started appearing in the previous build, but still occurs in this one. See below for a screenshot of the shaded region at the bottom of the page that is inaccessible. The cursor cannot be placed or moved into that area. Trying to move any text or math region into it just makes those items bounce out. Seems to occur when I've had a graphic on the page above that moved down until it no longer fit on the page and moved to the next page. Then it leaves this strange shaded area where the graphic used to be on the upper page. If I hit the carriage return on the keyboard, one line of the shaded region goes away. So if hit Enter a bunch of times, the region temporarily goes away, but comes back later with more editing. Any ideas?
Thanks,
Jason

To have an account it is enough just to register at http://smath.com using this url: https://en.smath.com/register
There are no any conditions - it just takes couple of minutes to fill in a registration form and receive an e-mail.

Exactly. I'm preparing to make a release of SMath Studio ver 1.0.

Long time ago I planned to provide more integration between SMath Studio Desktop and SMath Studio in the Cloud. In addition I want to restore functionality to create full featured SMath Viewer apps. All these requires support from server side. Which means every user who plans to use such functionalities needs to be authenticated.

Today SMath Studio in the Cloud stores Terabytes of worksheets and other data on server and it becomes more and more hard to maintain server/database (performance, backups etc.).

Another point is that I want to stop asking community for donations. Just to make it clear: it is a pleasure for me that so many people ready to help and really helped me a lot, but obviously it is not a way to make a project more professional.

Taking everything into account I decided to try to change something... and to introduce subscriptions. Preliminary, there are 3 options to be available:
  1. Simple: SMath Studio in the Cloud in guest mode, SMath Studio Desktop will work as it does today;
  2. Existing account at smath.com: personalized SMath Studio in the Cloud, auto fill properties for new worksheets from the user Profile, synchronization of the settings, etc.;
  3. Paid plan (f.e. annual, based on the number of users in Organization): unlimited disk space on SMath Studio in the Cloud, full featured SMath Viewer Pro, deep integration with SMath Studio in the Cloud; additional documents backup options; support by e-mail/Skype.


It is not a final list, so something may be changed or rearranged. Of course I will provide special offers for those who use SMath Studio for personal or educational purposes.

And I want to highlight it again: SMath Studio remains to be free and account or paid subscription required ONLY for features which uses connection to server or if it is related to support. Just because I have to spend many time and resources on this stuff.

At least it is a plan. Not sure if it will become a reality. For now, having an account on smath.com enough for all.

Best regards.

Account at the Forum and account at smath.com are different. This is something I need to fix asap, but it is not that simple.

Thank you for your support on linux. It is not a growing market yet you do your best.
Actually one thing we really want is bold and italic font functions to work with linux.
Sign-in option has secondary priority compared to this at the moment if you ask me.

This is by design from the time when Pages representation mode was introduced. Please try to play with MS Word and SMath Studio side by side.

Wow, 20+ years of using Word and I never knew about that! Thank you for the explanation. I had tried clicking in the space several times but never double-clicking. Glad that one had an easy solution. Thanks! Any suggestions on how the text is displaying in controls?
