(Copied from bug 689092):

David Carlson: I think that if any register view filter is retentive, then the
filter active status should appear somewhere in the window of every
affected register view.  I would prefer it to appear in or near the
column titles, but the bottom bar near the activity indicator would also
work for me.  It also should be flagged visually somehow in the register
tab, without adding more clutter to the tab.  Perhaps a symbol (choose
one, tilde, perhaps, also with contrasting background/foreground colors)
next to the 'plus' that appears in tabs for accounts with sub-accounts
views.

Further, then each filtered view should have it's own tab in the tab
bar, and multiple views of the same account should be so identified and
allowed.  This would, however, complicate the decision of which view to
go to when a jump to account is requested.  Maybe only one filtered view
should be allowed, and/or a jump would default to an unfiltered view, if
no filtered view is available.  Currently, jumps never go to views with
sub-accounts.
