Any plans to update to gtk3 ?

[luzpaz]

Current dependency on gtk2 requires installing a whole host of old 3rd-party dependencies. So just asking if it's on the roadmap ?

No plan to upgrade to a newer GTK version.
The graphics library I used does not support GTK3 or GTK4.

GTK3 is also not present in the current minimum supported list.
FreeBSD/Linux:
gtk 2.24 for gtk2, qt4.5 for qt, qt5.6 for qt5, Qt6.2 for qt6, 32 or 64bit.

In the future I will add qt5 and qt6 release build for users who don't use 'Snapcraft' or 'Flathub'
