     - removed version history :cry:
 
+        % id = "01JDDE4YE6A70Q8WT8N3MVTK1G"
         + the quality of this feature was too low for my standards.
         this was caused by the treehouse's codebase being one giant pile of spaghetti, onto which bolting a version history feature only caused more havoc :oh:

             - if you've ever run across broken branch links, you can thank version history jank for that.
 
+    % id = "01JDDE4YE6VY4FWQ21H7X2VGQ4"
     - I refactored treehouse (the software) to no longer generate files upfront!
     instead, there's a _virtual file system_ from which the web server sources files.
 
+        % id = "01JDDE4YE6K43DMZZ9GGNYT5G6"
         - this virtual file system, or at least [the part that assembles the page as it's served to you][vfs target], generates pages lazily---which causes my dev experience to be _faaaaaaaAAAAAAAAAAAAAAAAAAAA_

             - generating all the page versions upfront meant I needed to wait over a second for the page to refresh, which made editing any minute details _really_ painful.
             imagine I did all the previous layout refurnishment with that...
