This is a really simple idea but it's one that has a tonne of uses: An individual opacity slider for tokens and images, perhaps beneath the tint-box. In an ideal world, we'd be able to edit the opacity of tokens both on the map layer and on the token layer. Token opacity sliders would allow for loads of subtle but handy features. You could make texture overlays and weather effects. You could create visual representations of transparency and stealth. It could also help for things like glass and forcefields. As it occurs now, when we want a transparent object, we have to create an interlaced PNG which can be a bit of a hassle. If we had a slider, it'd probably save a lot of accumulative hours in the community as we could essentially edit the opacity of a token we have rather than creating a new one or spending hours searching on the web.
