Firstly, make darn sure the material is of a sufficient armor rating to stop the penetration of an angry die throw
But seriously, when you say 4 panel is that 2 panels on the player side (the artwork, posted elsewhere) and 2 panels on the gm side (info tables)? That works for me as the tables I play at are often crowded.
If 4 panels means 4 panels on each side of the screen that's probably overkill. I too have the MT screens and much of it was useful but overly large, in print and area.
As for content I'd break it down as:
Must (well, should, to be polite) Have:
Combat Tables for personnel, vehicles, and spaceships (pc's are always picking fights) including a list of weapons and armors with combat stats (but not prices, wt., TL and the rest. That should be done ahead of time by players and gm's for the most part). And not forgetting some typical hard and soft cover factors, and camouflage.
A Skills/Feats list (just the name) with stats, average dc, and type(s) of checks (i. e. opposed vs ?, co-operative, synergistic skills, and if take 10 and/or 20 is allowed)
A Travel Times Table to/from orbit, 10 pd, and 100 pd (for each size world and a lg. and sm. gas giant), as well as between near and far neighbor worlds, based on maneuver G turns or hours.
All the credits, legalese, and logo work across the whole bottom inch or so. Visible, but not a loss if the papers and books behind the screen block it during a game.
Hmm, might be a trick to fit all that on just 2 pages
Optional (as if you have the room):
UPP, UWP, or whatever the current alphabet soup d'jour is for the alpha-numeric descriptor for a star system's main port. It'd be nice but, unless you've changed it, its easy to memorize. Personally I always made up a lightly detailed single page for any system the player's were likely to give a passing nod to.
Psionics Tasks. Lets face it they were never easy to get before so most gm's won't need it (and a few just hate it, no, not I).
Maps (of Gateway, or anywhere). Not all gm's will be setting their game here, and even those who do probably don't need the map all the time. Many games can be played entirely in a single subsector, system, world or even startown.
Trade and Commerce. We can't all be merchants, there's not enough business for everyone to make a profit. Its entirely possible to run a Traveller campaign without ever worrying about making that next ship mortgage payment.
Any and all the optional material above would be better (ideally) suited as a special Cover/Screen wrapped around your proposed "best of pdf" series and could focus on detailing that area of interest.
I have to say (nothing personal) that I can't agree with Neo (post above) on the character creation or the el/xp rules being on the screen, or his vehement opposition to weapon "combat" stats (no prices, etc., I agree emphatically), but I do like the idea of a separate index page.
Well this got a little long eh, way over my cr2 limit. Later, gotta see a man about a "package".
