Side note: Ok, my add-ons are now back (the SillyWeasel project ones for jQuery, coffeescript and a few other ones). You can see them with addon search or addon list.
I am tracking a potential issue with the update the Roo team did. My add-ons all showed up but one (the jqueryui one). I had done a addon search --refresh command and / or re-started the shell numerous times, but that specific add-on didn't show up.
To see them I had to do a rm -rf of <roo home>/cache. Interesting situation, and if someone doesn't see 39 add-ons once they start and do an addon list, I'd like to ask them to:
1) zip up their Roo installation folder
2) let me know
I can then contact the Roo team and let them know that I have a Roo shell in that state.
If you want the updated list of add-ons including the jQueryUI one, rm -rf your <roo home>/cache directory, realizing it may make you re-load your add-ons in your particular shell.
