The shortcuts for the tools are numbers, and thus not very intuitive

It is better to add an option to also use (underlined) letters:


L Line
U Curve
F Fill
T Text
C Circle
H Freehand
... etc

Or have an option to change the shortcuts ourselves ...

Thanks for your suggestion. I do plan on making all keyboard shortcuts customizable. Stay tuned...

Thank you!

Another suggestion is to add icons to the commands, it is easier to recognize an icon that to read a word.
The optimum would be if you can choose between icon only (for minimal interface), or icon and text (for clarity).
