Userscripts.org

In most desktop email clients, when you drag one or more messages over a folder which contains child folders, the parent folder will expand, giving the user access to its children.

It would be SWEET if your script could do this with gmail.

I am a programmer so I could try hacking this myself. Is this something you've thought about?

The obvious hurdle is knowing when the user is dragging something over a label, as opposed to a normal hover.

Maybe this will work:

1. Register for mousedown and mouseup on document.body
- Maintain a variable "mouseButtonActive" such that it
will be true if and only if the mouse button is currently
pressed

2. Register for mouseover on a label:
- If mouseButtonActive:
// Assume the user is dragging something:
- Set a timer to "expand" the label after ~500ms

3. Register for mouseout on a label:
- Clear any timer set by a mouseover

What do you think? It's not perfect and does produce a false positive, but only under pretty specific and uncommon circumstances. I'd be happy to work on this if you think it's worthwhile.

Thanks for this script! Very useful.

sorry, my formatting got a little screwed up. this is more readable:

1. Register for mousedown and mouseup on document.body
   - Maintain a variable "mouseButtonActive" such that it 
     will be true if and only if the mouse button is currently 
     pressed

2. Register for mouseover on a label:
   - If mouseButtonActive:
     // Assume the user is dragging something:
     - Set a timer to "expand" the label after ~500ms

3. Register for mouseout on a label:
   - Clear any timer set by a mouseover

Hi Arend -- did you ever try this? I'm just curious because if not I think I will give it a shot.

Thanks!
