v 2.1.0

I would consider this a v.2.1.0 pre-release more than anything as I'm still working on making the UI match across all the pages. There is a bunch of new features and fixes to some important logic which is why I'm releasing it before the UI redesign is finished.

Below are a few of the new features

1. Tags system
2. Minor UI/color tweaks
3. Global search
4. Priority filters
5. Profiles
6. New columns (tags, sale date)
7. Duplicate detection
8. Application no longer stops working upon the PC waking from a sleep state.
