Couple bugs fixed:

- Copying an old item brings it to the top as intended
- UI touch ups

It's pretty much solid now, though, time may tell things unknown to me
right now. But, if so, I'll fix em'.

It's ready for use, install this sh*t if you don't want to buy any of
those other ones that have nothing that this one does not (or at least,
this does exactly what Paste does and looks very similar)
