No, sorry - and I know that reply from another user with the "Still not enough?" quip is over a year old, I've just been unlucky the past couple of times that I've gone into the Autodesk Knowledge Network and found "answers" like that. The actual and frustrating answer has already been presented, which is that it's impossible to change the size or color of the snap symbols. So while unnecessary and not welcome, my comment was intended to remind contributors that the actual answer is enough, and anything that tries to belittle the question by implying that, "Revit is perfect - get over it newbie" just makes for a really uncomfortable forum. I see this all over the place with just about every piece of software I use, that folks on the forums seem to take it personally when someone suggests that Revit should do something that AutoCAD does really well in a similar fashion, or vice versa.
Anyway, I'll try to remember to take my own snarky reactions to snarky replies to the "let's all snark all over each other" corner of the Knowledge Network. Thanks for calling me out (not sarcastically.)
