Adding some form of tagging/rename/folder structure. Most scripts have obscure names and I often forget which script supports what champion especially with AIO's. Having to check website to find out which script I need, usually in an ARAM for example. Perhaps change the 'update' filter with the github urls into a section we can add notes.
An option to check for updates for all scripts in the left and auto update on launch.
Window resize would be nice, the corner element is there but doesn't function. I use a 3440x1440 Ultra Widescreen, it's tiny.
Add a Ready/Launch/Start button instead of the auto input box, little annoying launching GOS for it to ask to load into the process, clicking cancel to check for updates etc and then having to re-type the process. Especially when GOS freezes or crashes etc.
