Feature request: add ability to rearrange the positions of the notifications

[crok]

Hi! I use your app for my everyday life and really appreciate the work you put into the code. I only miss this one feature I'm requesting now: a way to easily rearrange the notification positions I already added. As a dirty workaround I used to add (or remove) spaces to the notification title or description and whatever I saved last will go to the first place so with some practice I can rearrange them but this is very clunky. Since it is actually possible I would like to ask you to add a long-press-and-move-around kind of rearrange method. Thank you very much!
