Previews is fine but not enough because they are often too small.
Another idea for that is to display the selected layer line "bigger"
than other. I'm thinking about the adept (see
way of display more information for selected line. We should have a
bigger preview and some complementaries informations (such as what is
locked, mask, etc...) than for other layers.

Actually, it seems to be very close to what I was thinking of, hide (or
fade/colorize/wathever) other layers than the current one.

The idea of mouseover the preview seems to be fine, but I think this
should be :
- unactivable (unless the operation is time transparent)
- activable by another way (switch button/shortcut...) in order to be
able to paint with this kind of display activated (this implies of
course using semi-transparent/xor color and should be a second time step)

Well, I prefer the photoshop approch, meaning CTRL+right clic give a
choice of all layers that are "under" the clicked pixel
(but it's maybe matter of taste, and honestly, I never use this feature)
Wathever, all what I read on this message sound really good :)
