Update the GUI look and feel to a WPF + responsive GUI
- The usage/look/feel is kind of clunky, with so miscellaneous delays and microadjustments, which make it feel slow.
- Several panels are having a 'not really adapted' display.
- A responsive display and adjustments would be much welcome.
- Adding a smart column adjustment (put the mouse cursor between two column titles, the cursor becomes a left-right double arrow, then double click will make the collumn adjust to minimum width without cutting the largest row) would be much welcome.
