Improvements I would love to see in Pano

[r1ck-s4nchez]

1. It would be cool, it has more metadata based classifications like from where it was copied, where it was used
   (lets say copied from VS Code and used in slack)

2. Still More Classifications for the code copied like JavaScript, python, bash

3. A regex based search option

4. I often copy a series of required data, so if I search for a particular entry there should be a way to provide the previous and next list of entries
