Using Moodle 3.9.9 with Boost theme and I'm asking specifically about this:
Version 18.104.22.168 - 02/07/2021
Added 'Toggle blocks location' functionality, thanks to John Joubert (https://github.com/John-Joubert) for the patch - #100.
Feeling dumb (again), but I cannot for the life of me figure out what the "Toggle blocks location" functionality is all about, mentioned in the Version 22.214.171.124 version information, since I can see no changes after playing with the new settings.
I checked out the github information: https://github.com/gjb2048/moodle-format_topcoll/pull/100 to try to understand and I've also checked any documentation that I could find, but I haven't found anything.
Maybe someone can post a picture of what I'm supposed to see? I hear it's worth a thousand words.
