page consolidation

under the tab at top ...where it shows pages. Is there a way to make a sorta folder to say all the maps of one module in it?

No, but it's on the minds of the devs and something they've talked about in recent Community Roundtables as something they want to do soon.

Thats good news to hear...doing deck plans would be more easy if you could group the decks of each ship in folders

If you are not using dynamic lighting, then making the map a multi-side Rollable Table token sometimes provides utility for stuff like that. If you are using DL, Kraynic's method will allow PCs to be on different decks but on the same Player Page, making it easier to "split the party". Best for smaller maps like ship decks so all the ray tracing doesn't bog you down.
