Over the past 2 weeks I've been slowly but surely working on the interactive move niri PR [1] by @pajn. It's already got me to fix quite a bit of tech debt in the layout code, which is cool.
The PR is still rough around the edges, but mostly works, and I switched to running the branch on my own systems to give it thorough testing.
(also no, this is not the Floating Layer yet, though it's a good step towards that)
Attaching a video of what it looks like rn
