So something that Qubicle 3 isn't doing that Qubicle 2.5.x did was remember the location to which I last exported a mesh. Every time I launch Qubicle, when I go to export a mesh in Qubicle 3.x, I must re-navigate my system to locate the directory to which I previously exported. This can be very time consuming, especially when the destination is nested in a relatively long path (for example: M:\Unity\Projects\5.6\PROJECT\Assets\Models......... and so on). I would like to see Qubicle 3 remember the last place to which I exported a mesh.
Alternatively, it'd be pretty awesome if Qubicle could set a "workspace" to which all files are saved/exported, or opened/imported, similar to Maya. The workspace would persist through exiting and relaunching the program, and could be changed at any time. Perhaps you could save workspaces which can be accessed from a menu or panel in order to quickly change between workspaces (for example, if you have multiple projects you may be working on at a time).
Just suggestions; I hope they are taken into consideration.
