Working with Tabs feature request

Tabs help organize things, but I’d like a few additions to the UI:
1 – Renaming Tabs
2 – Reordering Tabs
3 – Simplified moving puzzles between Tabs; procedures especially. With cut or copy and paste all the links to Trigger puzzles are broken and have to be manually re-established.
4 – Searching across Tabs. You can use the browser ‘Find’ function pretty easily, but it only works on one Tab at a time.

Jeremy Wernick provided a great tutorial on how to do the third one by editing the XML file in this thread:

Moving procedures between tabs

And with that knowledge, you can figure out the others, but I still really want this to be part of the UI.

Thanks again for a marvelous product!
