Android: drag and drop sorting

### Describe the feature you'd like to request

Hi
So currently the only way to sort the bookmarks in the Android app is to "edit" the bookmark and put it in another folder.

We cannot sort it inside the current folder to put it more up or down.

### Describe the solution you'd like

I don't know if thats an easy feature to implement, but a drag and drop function would fit nicely in the Android app.

For example I let my finger 3 second on a bookmark, the bookmark lights up to tell its been selected, and I can drag it somewhere else.

Maybe also the possibility to select multiple bookmatks by clicking 2 or 3 seconds in each one of them and then at the top of the page some icons appear:
-1 arrow icon for "Moving all the selected bookmarks"
-1 trash icon to "Delete all the selected bookmarks,
-etc

thanks for reading
