I like the use of saved searches. What would be really cool is if I could set them as display elements of the dashboard. So, I have my few boxes in there right now, what about adding a box "custom search" where I could then select my saved search from the config panel. Ideally, it would be possible to have several boxes with different saved searches there.
Eventually, the pre-configured boxes you have right now are some kind of searches as well - you might be able to harmonize the way these boxes work by just setting up searches for these as well...
Any chance we see something like that any time soon? I've seen that a major interface overhaul is in the works, maybe something like that is in there?
