Earlier quoted context omitted.
VS2010 has "Navigate to" on ctrl-, which is better than jump to file. It's jump to anything, type a class name, a method, a filename, a partial filename, partial anything, and it will match what you write against everything in your solution. It's really powerful and I don't click around in the source tree at all anymore.
While a vast improvement on the past, "Navigate to" doesn't find stuff intelligently like Resharper's jump... e.g. if I have a file "LabListView", I can type "llv" in the "go to" window and it'll be highlighted (I could type any combination of characters but I tend to use the capitalised letters). VS2010 just shows an empty list when I do that -- I have to type a complete partial name. I could also be imagining this,…
I believe Eclipse also does "best match based on previously opened files" (sort of heuristic/guessing) just like you guessed the way Resharper does it.
I wouldn't be surprised if Resharper added Eclipse's features that are missing from VS.NET being that JetBrain makes IntelliJ that competes with Eclipse.
Of course the best part of Eclipse is that it's free and you get everything :)
