align selected objects on grid

[Franck78]

Hello,

start with empty pcb

for comprehension, set grid to 100mils
and select "mm" units

create a square for egdescuts, 100mm x 100mm ,top left at 0,0

select your square and move it somewhere in the center.
top left is on a grid point, ok, good

change grid to 2,5mm

select you square again, you cannot align it to the grid
-this is the bug

The story here is you don't really care of grid size at startup.
You are focused on drawing your edges (at least me) then moving that away from the red lines
(but you want to keep the red lines as ref)

-improvement one : make sure grid size follows the unit selected until the pcb have his first object, with a decent human 100mils or 2.50mm size

-improvement two, optional, use the very first mouse rectangle interaction to define a rectangular pcb edgescuts set. With sizes being shown in big font saying "creating initial pcb edges 9,8mm x 22mm"
It is so frustrating to have first mouse interaction doing nothing when obviously this can be done.

-improvement three : end the mouse operation with a contextual menu saying
--create edgescuts
--create edgescuts & planes zones, because zones are another painful things to create.
