It would be great if the function of creating folders was added to keep the stream better organized
yes please! I would love that
The possibility of creating folders where to insert the lines inside them and being able to move and modify them together
I believe you have already hinted at grouping or folders for layout. It would be handy if that folder could also update your stream info.
For example, if I access my game folder (PoE) that has three layouts in it (Starting soon, BRB and live) and select one, the parent folder should be able to automatically set up the stream with the correct game, category and tags, even the stream description.
Agree with OP. It would be great if you could organize your followed channel list into different folders that could be re-named into different categories i.e. music streamers, Hearthstone streamers, Tarkov streamers etc.
