Thanks, this looks good.
Sortable columns is great. The information looks easy to follow now.
The right click options seem to have disappeared now - used to have "Open in folder" and "Prelisten" as the options.
Personally I didn't use prelisten much but did used to use Open in folder occasionally.
Regarding the ads in the column, what would be good is if right click contained the edit and delete options, for each item listed.
And separately, for keyboard centric setups, if you scroll down the ads list using your keyboard, pressing down, "Enter" would be a logical 'edit' key, and "Delete" key would be a logical delete key (defaulting to "Yes" in the "Are you sure?" prompt). Or perhaps Alt+A for add, Alt+E for edit, Alt+D for delete as an alternative.
Currently we need to double click on each line or click on the edit button each time. For setups where a mouse isn't easily available that can be a hinderence as you need to tab down to the edit / delete buttons for each item.
Separately, in 'Ad Properties', the tabulation order is a bit all over the place. Would suggest that gets reset to
1. Active
2. Start
3. Start date
4. Hour (start)
5. End
6. End date
7 Hour (end)
8. Priority
