I've been using Moodle more and more recently, and the ability to reposition blocks is one thing which I find quite time consuming. Would it not be easier to tell a block which position you want it to be in once, with no more 'up', 'down' or even 'to top/bottom' clicks required?
The original idea was one which immediately sprang to mind, however there may be better options. I appreciate that the idea may have limited appeal and may make the blocks cluttered.
I like the way you can move an individual item anywhere else on the screen with just two clicks: one initiates the move process, and the 2nd (when the page has reloaded) puts the item back down. I would like to be able to do the same with blocks.
I'm now imagining a different system to the one I initially suggested. When in Edit mode, each block has a drop-down menu appear, with the block's position from the top listed in it. Changing a block's number moves that block to that position, and reorders the remaining blocks.
You could even include 1L, 2L, 3L, 1R, 2R, 3R to move the block's position top-to-bottom as well as left or right.
I have added this idea to the tracker with an appropriate screen-shot of roughly how it could work (taken from Blackboard but I'm sure you'll see what I mean).
Left pane: the 'before' shot.
Middle pane: drop the menu down and click on '1'
Right pane: the 'after' shot. Note the bottom option moved to the #1 position.
