Here is a refinement of his ideas:
The room number and name are in the first row of the information box, then the dimensions of the space, with an orientation of the far wall. Special room shapes (i.e. circular) are mentioned here. Then information is presented about the room contents, and sensory information when needed. This information is sorted by "obviousness", so that what the PCs would first notice when opening the door is listed first, such as a coffin on a dais, or a slavering baboon rushing for them. The information is divided into three columns, the first being "Obvious", the second "Detail", and the third being for the DM's use. The column color shifts as well, to help you keep it straight when reading the text.
For example a painted wooden chest is obvious, that it has a dwarf made brass padlock is detail (that the players would get during examination), and that the chest is trapped with a poison gas, and contains a jeweled skull worth 100gp is for the DM's eyes only.
Picture of what this looks like using one of FrDave's examples:
Anyway, nothing groundbreaking here, but it may be helpful when you are in the heat of the moment. Thoughts? Comments? Refinements?
