But it has a few problems in terms of usability the major one that would be nice to get addressed at some point is GTK. Getting inkscape to run on macos for instance, requires X11 which creates a really bad integration with MacOs itself. The solution is Qt, probably this is one of those initial decisions that Inkscape devs regret everyday.

Gradients is another example about bad usability, try by yourself to add a new step to the gradient without smashing your keyboard/mouse. Turns out the solution is googling it which gives a solution for that, however you will eventually forget about that since it's non-sense (then repeating the same cycle again).
