Maybe I did something wrong (SDL2 instead of SDL3 or something else). In my test the main window was not resizeable. Also I had some problems with the Xft text rendering. When text was redrawn, it was not 100% cleared and there were some artefacts from previously drawn text. I had this effect in the text widget, but also in the menu bar. I also had problems with opening sub-menus. Have you tried it yourself and didn't have these issues?
I have only tested it on macOS. It looks very promising, but it wasn't fully useable yet.
By default xnedit should already use TrueType fonts for menus and other UI elements. If you have modified your X resources, it is important to use FONT_IS_XFT as fontType.
replace usage of ParseXftColor with AllocXftColor2
adjust lib flags order in generic makefile
