Additional Information
Feel "I found it"
-For thousandth time, when assigning master quality item by master quality item on each of 100 Dwarves in your military, because there is no material quality setting for materials in military menu. Every single master quality item has to be assigned individually.
-Not to mention assigned items are not automatically dropped to the bottom of the list of available items, but stay on its top, because of their high quality.
-Not to mention Dwarves already assigned to other squads pop up in list of free recruits to be assigned into new squad.
If only military menu could be resized like caravan trading menu in Depot. All menus actually are resized with resized screen, but the tiny lonesome military menu.
I tried searching for bug report with "military menu", "military screen" or "military display", but I couldn't find any such. Hard to believe. There should be some bug report already about this bug. It is kind of huge bug after all. Visually for sure. However I am told it is not a bug, but feature of sorts from ancient DF times. DF, before 0.42.01, used to be alike in all menus. Very tiny in upper left corner for every single menu in DF. I find it hard to believe, but then I was playing DF only for last 2 years. Also I am told if there is a hope to fix this visual interface bug I better post about it here among milliards of suggestions for new features.
Oh well, but imho it is still a visual interface bug and not some new feature. It does negatively impact Dwarf Fortress. Particularly that players need to access this menu so very often, because of entirely missing usability features in it.
