Hi @Jeremy Best, thanks for your suggestions! I agree there is basically no big need to alter size of icons, text is enough.
One simple and handy alternative solution could be a few new "info-tools" - just like you get acquisition hints when you fly with the cursor over an object, or get the class info when you fly over the drawing with the eye tool, it would be great to have one or a couple of general "info" tools;
1. a tool for basic information: coordinates (x, y, z), same as now can be read with small letters in the message-bar. Maybe class and layer.
2. a "data-info tool" that tells all what you see in the info-bar when you fly over a door, a stair, a slab or any other object with info.
Those two tools would greatly help to organize and check the drawing, safer and faster than marking objects to read info-palette info, and it would also be without the risk of accidentally change or alter the drawing, that marking a object always brings... and cursor hints can be set in size already, as you point out :)
(Another positive side-effect is that such tools would come handy during skype meetings when using screen-share, a every-day part of our workflow...)
Your suggestions to alter resolution affects all programs and comes with less good picture-quality, at least on mac. There are some other options available in the system, but non works without unwanted side-effects... so I think this should and could be solved within the program.
