I don't know if it's just me, but I find the flagging history filters incredibly confusing. Here's what mine looks like:
Maybe I'm an anomaly, but it took me years until I realized what was going on here.
Rather than mentally grouping things between the white space (e.g. "1 spam flags" and "1 declined" go together), I was grouping things between the horizontal rules (e.g. "51 helpful" and "1 spam flags" go together).
Is there a way to improve the UI/UX?
The first obvious thing that comes to mind is to increase the whitespace even more, but that could be an obnoxious solution. What about using a table-like structure instead of a list? For example, the comments flag block gets moved to the right of the total post flags block (or something along those lines).
Anyone agree, or have any suggestions?
