MUVWSG: some (as main) windows not resizable, notably too small

[Destiny Architect]

MUVX3W: (copy MUVSIN): I witnessed in (all versions I used=the present version ms_lts_precise_r8.iso and the prior one)
MUVWID: In the case of the MS tab, , this prevents one from fully seeing each boot menu item without having to scroll left-and-right, including important distinguishers, as if persistent and how much, are easy to miss.
MUVWME: *In all good software, every window should be re-sizable including enlargeable to the size of its contents or the containing window/screen whichever is smaller.
MUVWWK: **Including by default set to this max practical size unless some of the contents is pretty much always low-interest then that can be scrolled out.
MUVWOW: **Yes small windows are cute on quick glance, appearing small & sweet, but they don't do this MUVWME they overall become annoying, and in some cases notably hurtful to productivity..

It's unusable as is. wmctrl was unable to resize it as well.
