I used this for an incredibly long time and I absolutely love it!! Unfortunately, I had to reinstall OBS because it was screwing up, and I lost this plugin, so now that I've just reinstalled it and it took me like half an hour maybe because I hate Github because it's confusing, but I managed to find the plugin download, and I discovered that the presets are in different folders, so I had to install those separately from the actual plugin itself! Sadly the qwerty preset was unavailable, which is the one I always used, so I uh... May or may not have just dug through the files, downloaded the image of the keyboard, and copy/pasted the .json file for it that was in there. When in doubt, make do with what you've got I guess LOL.
I initially felt stupid but then I did a thing and it worked so now I feel smart, 10/10, my favorite plugin on OBS (and not just because it's my only one)
