Textualize/textual v0.77.0

The lucky number 77 release

on GitHub

This is quite a large release!

We've done a lot of work on the command palette to make it easier to work with and use.

We've also added a "help panel" which you can summon from the command palette. This will give you context sensitive help, and a summary of all the key bindings. Here it is in action:

Also in the command palette is a "save screenshot" command, which will save a screenshot of the current screen. Very handy for adding to documentation.

There are a number of other smaller changes, fixes, and a few breaking changes. See the detailed release notes below:
