For media content I do not need to see these columns: Attr / Dimensions / Duration / Video Codec
I right-click on any column in the top/parent folder and click "More."
I remove the aforementioned columns from the right selection box.
I click Apply.
I click on the "Save" button at the top and choose "For this folder and all Sub-folders."
I click OK.
I exit and restart OPUS.
Columns reappear.
This is tied in somewhat to my older topic, which has never been resolved. So I am basically tired of looking at these refreshing columns when OPUS is open and would rather not see them at all.
