Primary goals: - Scrollable output ( fixes #245 ) - Sending job signals from status view - Filtering of output by filesystem Implementation: - original TUI framework: github.com/rivo/tview - but: tview is quasi-unmaintained, didn't support some features - => use fork https://gitlab.com/tslocum/cview - however, don't buy into either too much to avoid lock-in - instead: **port over the existing status UI drawing code and adjust it to produce strings instead of directly drawing into the termbox buffer** Co-authored-by: Calistoc <calistoc@protonmail.com> Co-authored-by: InsanePrawn <insane.prawny@gmail.com> fixes #245 fixes #220
