Please: No more gadgets.
Focussing on what the gadgets tell you is the traffic is itself a problem. Gadgets have delays, margins of error and sometimes fail.
E is an "abomination" but 'G''s OK, because you know you have to keep your eyes peeled in 'G'? I've some (very old) news for you: You have to keep your eyes peeled in every class of airspace. At least in E there is a 3rd party who has the job of assisting IFR not to collide with whomever. That's what you heard when that VFR "blasted through" Class E airspace while on the "wrong frequency", isn't it?
