(I don't think the menus are bad, I just think they could be improved)
Some elements in the electronics, powered materials, sensors, and force menus seem like they could fit in more than one of those menus. For example; why aren't GPMP and PUMP in the force menu? The sensors menu only has 4 elements in it, so maybe it should be combined with another menu, like powered materials or force.
FUSE and FSEP seem like they should be in the explosives menu, and moving them there would also make the solids menu less full. Gold also seems like it could go in electronics, because it has unique electrical properties, but that menu is also full, so maybe it should stay in solids.
A lot of menus are getting filled up (Electronics, Solids, Game of Life), so maybe it's time to make a new one, like a life (not Game of Life) menu, with PLNT, VINE, WOOD, VIRS, STKM, STK2, FIGH, and maybe TRON.
Another way to solve that problem would be to make the screen a little bigger and have 2 rows of elements at the bottom. (The area where you can build stuff would stay the same size)
Also, I think that the "hidden" elements (except LOVE and LOLZ) should be added to the menus, because that would make them a lot easier to get. If there were 2 rows of elements, then they could fit, even in the menus that are full now.
That's what I was thinking about 2 rows!
I got 1920x1080 so I'm fine. Try fullscreen it will fit to your screen.
