I think I found an issue. The help page shows s to be bound to pause rendering, but it does not work. The UI and values continue to be updated.

There doesn't seem to be a case for s key here: https://github.com/pesos/grofer/blob/86954fe342c20c58c64535acd6cdd32aab6ee103/pkg/sink/tui/container/overall_container.go#L178

Oops, I probably missed this in the UI refactor, will fix.

Edit: The functionality exists, it's just p and not s

I noticed another issue related to pausing. This happens in both proc and containers. When the UI is paused (using p) and you open the help widget (using ?), when you go back to the main page (proc or containers) (using Esc) it gets unpaused automatically.

Is this expected behaviour? I couldn't find anything that would unpause the UI when pressing Esc.

This is probably because a selection happens to perform an action/kill. Esc then deselects it. I'll fix that in the next commit.

@Samyak2 @MadhavJivrajani changes have been made as per comments, additionally, an error box has been introduced to replace the error cursor colour for the proc page. Let me know if I've missed/need to change anything.
