Hi Dears
I just post this issue here (https://moodle.org/mod/forum/discuss.php?d=428672) which one of community members is mentioned that perhaps I'd better postit here:
One of the things that I face to it and make us confusing is the place of "Add a block" when turn edit mode become ON. User should goto the end of Side panel, therefore in some courses with many sections, user should scroll a lot to reach the end of Side panel items to click on it, to add the a specific block on the other side of page.
On the other hand, when we add Blocks in boost them, always they are on opposite of Side panel (in dashboard or in courses) , so I think it makes sense that if the place of "Add a block" button be somewhere around the place of added blocks or side by side of new icon for blocks side, when "Edit mode" is on.
These are some ideas:
