I know you can easily delete/add mods to an aternos server, but it would be awesome if there was a UI to quickly enable/disable loaded mods. This could helper server admins quickly troubleshoot/test mods, especially with version updates. For example say the new minecraft version breaks several mods I like to use but it's more important to me to update. I could remove them but then have to manually keep track of updates and add them back in.
I'm envisioning a UI in the MODS section that shows loaded mods and lets you enable/disable/uninstall the mod directly. Similar to how the OPTIONS UI simplifies access to the common server.properties settings, the MODS UI could simplify mod install/uninstall and unify mod management to one place. The one downside I can immediately see is an increase in unused server storage if the mod is left installed, but aternos already lets you add files/folders to the server so maybe that's a non-issue. If it is an issue then maybe this could be an exaraton only feature. Or alternatively the mods UI keeps a list of previously installed mods and disabling merely uninstalls the mod while leaving the list entry, whereas uninstall would remove the mod and remove the list entry.
Something like this:
