So as of right now, there isn't any way to uninstall mods easily. You have to end up reinstalling the server or software, which isn't convenient for most people, ESPECIALLY those who will need to use mods temporarily and then have to uninstall them later.
Here are two solutions to this:
1. When you go to the mods page, you first land on a page that shows you all the mods you have on your server, on which there could be "options" on each mod, and you can uninstall the mod from there, among other things. Then if you want to add a mod, a button taking you to https://aternos.org/addons/ will be there.
2. Just add a button on the page where you install the mod to uninstall it, if it detects that it's on the server
Any way works, but I feel like it should be added.
