[screwys]

Submission checklist

• I have searched existing issues and confirmed this has not been requested before.
• I have checked existing pull requests for similar changes.
• This is about a community plugin, not about Noctalia itself (those belong in the noctalia repo).

Plugin

procmon

Feature type

Accessibility improvement

Feature summary

Allow a way to focus filter directly, which can be provided with a type to search toggle or a keybind (for example plain f like btop does), which would help for keyboard usage of the plugin

Motivation / use case

Process monitors allow easy way to filter processes and this is likely a behavior a lot of people got used to. btop enables f keybind, and GNOME apps do have type to search feature

Proposed solution

keybind or a toggle
