Foundry VTT issues I'd love to have resolved

Here are few things that trip me up in Foundry VTT with the GURPS module:

- light sources. I really want to be able to turn on light sources for DF and have them just show up . . . and show the dim areas - where there is a penalty to rolls - to clearly show up. Otherwise, everyone assumed bright = bright, and -0. That's not ideal.

- walls. I'd love the "walls" layer to be visible while I'm on other levels. Or just have an option to make walls visible to players, not just block light.

- visible margins. I'd like to have an option to make a roll, hide the roll, but reveal only the margin of success to the players. Something like, "Norker rolls . . . makes it by 4." That way I can roll contests and have visible results, but not visible skills.

Overall, though, as we've gotten more skilled with the system, it's become much easier . . . and it's a versitile base VTT with an excellent rules package on top of it.
