So, I'm looking at my billboards page, and honestly, I have no idea what any of them are. There are a couple of different things I've used billboards for over the years and I can't say I really know which is which. On top of that, some of them are useless to me at this point and don't even need to be in the mix.
That said, I think it'd be useful if I could view the content of my existing billboards and delete the ones I know I'm not going to use anymore. I'm imagining deletion as being an option only available on 'expired' billboards, so it isn't complicated by leftover impressions or anything. Maybe a name field for the billboards can be added so we can just go to the page, see the name 'Trick or Treat' or something in the same little block with the impressions and clicks, and know at a glance that it's the one we want to reactivate.
I haven't made a billboard for a very long time but I can see this being very useful.
It does mean subeta hosting all those used billboard images though. I don't really know how much space that would take or server power or what have you (as you can tell i'm not very tech savvy).
