Slightly pertaining to this issue and referencing to my last Post
on the OP of this feature:
Due to my physical impairments, double clicking constantly is very taxing for me, I've been hoping for a similar implementation.
With the click to play feature in mind, multiple buttons on the cover displaying when hoovered could be configured to do certain functions such as Play, Open Containing folder- as well as many others.
These buttons could be in each corner, as well as a larger button in the center or a form of edge clicks as per Hiccup's suggestion. Button/click area function configuration can be to the users desire- mine would be a big middle button to open the album in Album/Tracks view rather the double click, a click to play button or a click area to do so and perhaps a Open containing folder button/click area.
I also have had another idea I have and am unsure whether to mention it here or in a separate post is allowing the middle click navigation function to be reconfigurable to left click... but I just realized that would cause issues when trying to click a track to play it- it would need to apply to album thumbnails only.
