+        - therefore the treehouse now has a vim-inspired (...vimspired!) command line (or, put more modernly, _a command bar_---except my commands can take arguments, because hell why not.)

+    + you can trigger the command line by hitting `<kbd>:</kbd>`{=html} on your keyboard, or if you're not on a desktop, press the little `:|` button at the bottom.

+        - I'm a little annoyed how mobile browsers display the command bar at the moment, but it's likely [we'll have to wait about another two years](https://caniuse.com/mdn-api_virtualkeyboard) until we get progress on that.
+        oh well.

+            % id = "01JESCRT219MEDNWMS52K78FA5"
+            - maybe I can make it work _at least_ in Chrome in the meantime.
+            won't make me, a Firefox user, any more happy, but that's still a fair amount of market share.
+
+    % id = "01JESCRT2139DSQX0KDH16VCSG"
+    - this was intended to be a dev mode only feature, but it feels too good not to use it for a feature dump for anything that might clutter the main layout...

     - internals: branches are now based on flexboxes rather than background images.
     this requires sending a bit more HTML, but [the layout is a lot more stable][branch:01HP20D2R4F2XZVBBQNVW6CVHE] as well as being [easier to extend][branch:01HP20D2R4C0DZAKKB84FCQNXN]
