This is my attempt at an oldschool, beefed-up desktop app for Lemmy for those of us who yearn for that kind of experience.
Currently it only does reading, if people use it I’ll work on comment support too.
If you want to give it a spin, you can download the flatpak file from here and run it.
it kinda looks like they’ve built it using windows forms which iirc defaults to a windows 7 design style when previewing it (i could be wrong tho)
