This happens at all places where you can choose directory to store files, torrents, when a new category is used etc. Directory choosing dialog always open at root.
(1) If the location has been previously set (or default is set), directory choosing dialog should open at the location where it has been set, as all the mature apps do. There are no shortcuts and nothing is more annoying than having to click deep into the path again and again for little changes. Should be easy fix.
(2) There should be a way to copy&paste the initial path (Why a system dialog cannot be used BTW? It has all the advantages ...).
(Just moved out from uTorrent to Tixati, great job otherwise. Thank You.)
