Let me make some coffee and see if I can summon the courage to turn this into a dropdown (unless you have other ideas). I think it's like too hideous/unwieldy to ship as-is. I think it's good that this mode exists, but it should be in like "Filter > Advanced Filter...", not "Filter".

Also, I'm going to fix that "absolute" thing by just popping this up as a dialog. So "Filter" would become a dropdown menu:

[Filter Tasks v]
(Open Tasks)
(All Tasks)
([saved stuff goes here eventually])
(Custom Filter...)

The last one pops a dialog with the full filter UI.

I can just put a couple of prebuilt filters in there for now and skip all the saved filter stuff, which should make this reasonably manageable.

It's interesting to me how these questions change if they lived in a Workboards application. Things like global filters, etc, make more sense there.

My sense is people would potentially want different filters for different projects. That is, a Sprint Project would maybe show closed tasks, but not a more standard Security Project or Design Team project. Perhaps having a global default in and a local override (not implicit sticky).

At least, it seems easy to start with a Global Filter across all boards, then see if there are reasons for local views. Local views could also just be covered by Dashboards.

Lots of possibilities for improvement but these are a lot of work too!

IMO it's already great to be able to filter tasks in the boards. A couple uses I can think of are to only show tasks assigned to a given user or to uncheck the "open" checkbox in the filter (since I assume the default filter will be "show all open tasks") to make closed tasks visible again.

It might be worth to release this implementation as-is and see if there's even a need to customize the default filter and / or save filters across boards.

The work on dropdowns a couple weeks ago made this relatively painless. Here's the new flow:

Default view: shows current filter.

Open dropdown:

Pick a different default filter:

Advanced filter:

Advanced filter applied, shows as "Custom Filter":

@chad, the one issue with this is that setDropdown() (and the "open" state of the button) look glitchy when the item is rendered in this context. Those should be pure CSS fixes, I left you a TODO.
