> Is there anything about it that would discourage its use for a standard desktop GUI app?
Complete lack of accessibility support, particularly for blind users via screen readers, in the included GUI toolkit. Please don't use this for any application that people will be required to use in their job or education.
Also, to be clear- the custom GUI library that the IDE uses is NOT a general-purpose GUI library; it is a support library for the IDE and other BeefLang tools. A true general-purpose GUI would be quite a lot more flexible and also much more complicated... which is not something that is intended for this particular GUI library.
I did eventually find that notice in the documentation, after I posted my comment (and sent you an email). I should have read more of the docs first.
Still, I wonder why you chose to write your own GUI just for the Beef IDE (and installer) rather than use an existing general-purpose GUI. Were you aware of the accessibility issue?
