Is your feature request related to a problem? Please describe.
A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]
The interactive view does not allow to identify whether a filter is in place or not.
Especially annoying as reset action does not clear the filter (but that's in a separate bug report)

Describe the solution you'd like
The fact that a filter is active is explicit and visible, and possible the filter rule as well.
Maybe added tothe bottom line.

Describe alternatives you've considered
Alternative ideas to display it :

• add a 'filtered' word in the column title for the processes.
• adding a second line at the top, providing the filter value
