So we've definitely considered a search within the expenses dialog:
basically a "keyword filter" that only shows expenses containing that
keyword. That's planned but not in place yet.
But we haven't really put the foundation in place for a broader search
(eg, "show me all reports containing this keyword").
Is the "search outstanding expenses" feature we have planned adequate
for you, or do you need full multi-report search? Basically, what's
your dream search feature, versus what's good enough for now?
