The project browser has been around for ages with virtually no changes or improvements, its high time it was replaced with a more modern user interface.
There are a lot of new features which could be added, these include:
- Separate out the family and Sheets nodes to separate tabs.
- Instant filter search
- Ability for sheet numbers to be made up from multiple fields
- Ability to press a button and find the currently open view.
- A button to quickly toggle views not on sheets.
I'm sure you could think of other improvements to add...
