Request Movable Columns on WP List (Reopening #431)

This is a duplicate of #431 which I feel was closed prematurely last year. Actually the situation has gotten worse since I first posted this issue. There used to be several adjustable columns, and now they are all fixed.

To maximize the space for the map, I want to be able to rearrange and resize all the columns on the WP list.

All columns are a fixed width, and they contain a lot of wasted screen space. Especially the "Command" and "Alt" columns.
Ideally I could move columns that are less essential to the right side of the screen . I do not need to see the Lat/Long or parameter columns during flight. When flying a mission, I only want to see:
1) WP number
2) Command
3)Altitude
4) Gradient
5) Distance
All other columns could be out of view to the right. This would save a tremendous amount of screen space for the map.

Thank you.

No source file, test, or entry point is named. Start by locating the WP list in Mission Planner and compare its current column behavior with the requested layout. Done means users can rearrange and resize columns, with less-essential columns movable out of view while WP number, Command, Altitude, Gradient, and Distance remain available.
