Yep it seems it boils down to personal workflow: I rarely use a mouse to manage the desktop environment while you would find this awkward.
I think that the least we can do it propose the OP our solutions to this, as the issue is not clear enough to propose a feature request.
My temporary solution would be sharing how I do everything with keyboard shortcuts.
My long term solution would be an overhaul of the grid which comes with the new Overview; we are discussing it here and I recently posted a mock-up of its possible behaviors: Automatic virtual desktops management
For me this concerns automatic behavior, but we are discussing on how to repurpose the new grid to make it work as the past “Present all windows” effect, and I’d like @ben2talk to give his two cents.
