How to re-order folders once create

I don't know if that's the right forum to ask but seems the most fitting one. In my game I have created various folders to organize my sheets, monsters, handout, rules etc... only to find out at the end, that there doesn't seem to be a way to order folders? At least I can't find one. You can drag and drop content inside folders and from one to another but how re-order the folders itself?

You have to drag the folders by the name and move them up and down. It can be rather tricky to do but it is possible. I wish that there was a simple toggle to organise the folders like you can with their contents. A to Z for example but manually seems to be the only way to do it for now.

Drag from the +/- image to the left of the folder name. This is a handle that lets you re-order. Similarly, the icon of a character or handout performs the same function.

OMG - I tried this like hell but couldn't get it to work. But actually getting exactly for the +/- makes it work. Thank you!
