Thanks Andrey Ivashov for this wonderful tool that you provided.
It is designed very well and the best opensource alternative to MathCAD available.

Please note: - There are some known bugs with Worksheet scrolling - will be addressed soon;
- There are some UI issues on environment with high DPI (some Custom plug-ins may not be scaled correctly).
Please use the following to disable high dpi support if required:

What about the indefinite integral ?
5346 had the the indefinite integral in the f(x)menu, thus available for maple.
It was removed 6179, but it could be called within maple maple(int,)
This last facility does not work anymore.
About that, Davide replied 19 days ago:
"I cannot reproduce the autocomplete of int in any SS version, neither changing the date on the machine, and I'm not aware that there ever were such behavior...
however, I don't think it is a desirable feature; how would you access or create any int~ variable/function if the program triggers the autocomplete while you are typing? (and imagine this extended to any function...)"

To all developers:
As you may notice starting from build 0.99.6955 SMath Studio supports high DPI and in order to scale Regions correctly we have to introduce new requirement:
- Plug-in must use SMath.Drawing.Graphics instead of System.Drawing.Graphics everywhere.
or
- All Fonts created by the plug-in must have GraphicsUnit.Pixel specified as a unit and size must be multiplied by 96f / 72f in order to convert Points to Pixels.
All existing plug-ins should be updated according to this requirement as everything looks ok while system is configured to have use 96 DPI, but in all other cases scaling of Fonts in plug-ins is incorrect.
All modern platforms like iOS, Android, UWP have Pixel specified as a unit by default, so this issue appears on Windows machines only (we have it on Linux as well because of Mono).
Please let me know in case of any related questions. If you are not able to perform changes by yourself - just let me know and I will update plug-ins by myself.
Best regards, Andrey Ivashov.
