Other question - do we want to differentiate checkboxes for subscriptions and checkboxes for filters? A while ago the checkboxes for filters were slightly indented to the right. Maybe we want this back?
I know you decided against having them "slightly indented" but I think some way to "differentiate checkboxes for subscriptions and checkboxes for filters" is an excellent idea. It makes it easier to glace and the window and know exactly what is going on.
With subscriptions you have a bit of a gap between the main tick box and the filter tick boxes because of the subscription update details but the user created filters don't have this and it makes it even harder to tell them apart.
