I went into a workspace and to the submission tab and I type in a filter. I use a string of the wdl's name to find submissions only of that WDL.
I later logged off of FC and then into it again and went to a different workspace. I went to the monitor tab to find a submission but my list was empty! I saw "There are no analyses to display." I was concerned that my submissions were gone or deleted!
BUT then I looked at the bottom of my window and I saw "0 - 0 of 0 results (filtered from 325 total) Prev Next" and then remembered the filtering text and then deleted the filter and then saw all the submissions.
I had two different tabs open, each with a different workspace and monitor table, played with the filter text and observed that changing it in one tab, then refreshing (open-apple+R) in another tab that the filter propagated that way.
If filtering is used, then it would seem like a good idea to highlight the "filtered from 325 total" text at the bottom of the screen. One idea is to make the monitor tab filters be remembered on a workspace-specifc basis so that one monitor tab's filter text/string wouldn't apply to the monitor tab from a different workspace.
