Wow Amos, thanks dude. it's good to hear you enjoy my posts.  I'll try to continue to match your expectations. I have a couple more ideas I'm excited about just need to juggle my time a little better to get some more work in.

In future, I think I'll try to write some extra notes as I go because when I've finished a round of updates it's difficult to remember which parts were a challenge. There was nothing particularly difficult in this set of changes but it was quite time-consuming. The biggest struggle was probably the comments section, I had forgotten how many moving parts the comments thread has.
