It'd be much appreciated if you could limit the time range when using the Problem-Widget with "History" selected as the category.

This way, the amount of displayed issues could be reduced to a minimum whilst ensuring that all recent issues are still being displayed.

Else, assuming you've got a well working environment, there might be a cludder of old issues from weeks ago which aren't relevant anymore or - to limit that - only display the last 20 issues or so, possibly missing some relevant issues if everything goes haywire.

Bottom of the line:
The option to set a time range (eg. last 7 days) and an option (or fixed setting) to show issues anyways if they're still active would be much appreciated for the Problem-Widget, when set to show "History".
