that's fantastic news about the quicksearch! Thank you so much!
About multi column I can only assume it's a tough feature to implement: a couple of years ago I was working as a writer for a Linux magazine and since I'm big into productivity i wrote some articles about file managers and did an interview with the Krusader team, and I'm proud to say in the process suggested some features which I think added a lot, but multi view even many years later I have not seen to have been added though there too many people were requesting it, so I can only assume it's a non-standard or tough thing to implement in the software. Still, it would be oh so very great to have it! In the case of those folders with many files it uses in a useful way a lot of the otherwise wasted screen space thus helping with a quick overview of where you are and what you're doing there, not to mention the increase in navigation speed as you go from one dimenion up-down to 2 dimenional movement.
