This is still a work-in-progress and was mostly made for fun. All it does is read from a list of files in ~/.config/rblx_launcher/ and display them to be clicked, launching xdg-open with the placeId.
The files (friends.txt and games.txt) are formatted like so:
Name
ID
%
It looks a lot better than current Roblox launcher, good job. Will you want some assistance in translation? I could translate it to polish
