Hello. I am another Tube Atlas user, not Appbreed support.
Maybe this is what you need... if you have the channel's videos in the Videos tab of Tube Atlas (there are a few ways to do this), you can sort by the Published Age column to get oldest to newest or vise versa.
Is there something else you were looking for?
Hope this helps.
Recently youtube removed the tab to see the oldest videos on a channel. Would love if you can work that into Youtube Atlas.
I love your softward and esp. youtube atlas. Thanks for the execellent service that you provide from an awesome software to the excellent tutorials for that software!
