As with the standard queue, I want see techs in different color, if they are available for direct research, when queue completed.
I mean:
- if we have tech tree:
A
..=>B1
....=>C1
......=>D
....=>C2
..=>B2
- and I have already added following to your queue: A, B1 (both not ready yet)
- it should mark B2 (can be researched after A), C1 and C2 techs (both after B1 tech) in a special color, that it can be directly researched (without intermediate techs) after my queue finished.

PS standard queue uses orange color for that techs. But you use this color as for items, that already in the queue.
Could you replace the color from orange for an another one, and save it for standard behaviour (available techs)?
