I really dislike the new layout where it puts the categories into columns instead of merging everything (as it did before). Meaning now, there is a lot of wasted space. I am currently still running version 1.7.9, and was wondering if there were any plans to implement the old layout (as an option in the settings).

I just find it odd that you would alienate many people who supported you and even disable comments on curse? (not sure what happened there)...we love your addon Adirelle, just please give us the option for the old layout! :)

This wouldn't be "just an option", but supporting two code bases, with conflicting parts.
