mixed column filters: date & tag

[dictionarymouse]

It'd be nifty to have the ability to combine date and tag filters for different columns.
For example, I'd like to setup a board something like this:

"Morning" filter = Today ➕ #am OR undated ➕ #am
"Urgent" filter = Before Today (overdue) OR #frog
"Today" filter = Today ➖ #am ➖ #pm
"Unscheduled" filter = undated ➖ #am ➖ #pm
"Evening" filter = Today ➕ #pm OR undated & #pm
"Tomorrow"
"This week" (any date this week)
"Later" (future dates)

Thanks for this really helpful plug-in. I also would benefit from a combination of filters.
A second level filter could be easily done and would already help a lot. More could be useful as well.
Tag filters should have a polarity (including/excluding).
Example: Currently I would need a dated or undated column but without the tag "#wait". For tasks with "#wait" I reserved a extra column.
Maybe allowing additional tag filters would already be enough to boost the flexibility.
Kind regards,
Martin
