TL;DR
Please add a toggle to the achievement window to either hide or re-order completed achievements to the bottom to avoid scrolling a lot.What?
Please consider adding a checkbox toggle to the top of the achievement window to "Hide completed achievements" or similar.Alternatively another toggle like "Show completed achievements first" could also be used to re-order achievements so that completed achievements are shown last instead of first instead, similar to e.g. on the technology screen.
Why?
When playing the expansion and trying to get all achievements I constantly scroll down quite far to see the remaining achievements, especially with all the new achievements from the DLC.I rarely use it to check completed achievements and adding a mod for this would not work as it would disable the achievements.
Pinning 20+ achievements to the left side constantly is not really a viable option either.
