Now, admittedly I'd like to see an MFC-like cross-platform toolkit, where I could develop for this toolkit and easily compile/run on X11, OSX, or Windows, with the SAME SOURCE.
Oh, wait, there *IS* one! But yeah, it needs a bit more support with respect to tools, etc. from what I've seen.
MS: if you can "get on board" with what wxWidgets does, maybe devs will like you more? Just STOP IT with the C-pound-only, ".Not"-only, UWP-only, "spinning compass" directionless NONSENSE. Stick with one thing, make it better, make it cross-platform (and NO slurpware/adware built-in).
