It’s been a few years now since I switched to Wayland. I use Sway, a compositor based on wlroots, and apart from the sporadic broken Wayland application (easy fix: force XWayland) and Java application (easy fix: set _JAVA_AWT_WM_NONREPARENTING=1), it’s mostly been great times.
I have also been a long time user of UK International Keyboard, and that is the layout I know by heart and use on all physical keyboards. This layout builds upon the standard UK keyboard to enable you to type ṽårìóǘş kïņḑş õf åçĉëñţş äņḑ şẙḿbôĺş not found on the keyboard itself...
