[Bf-funboard] Critical improvements and features

[Ильдар Ахметгалеев]

This is how I use gtk open file dialog:
In most cases I already have file manager with my working directory?
When open dialog appears I drag-n-drop file or directory from file
manager to this file open dialog and it automaticaly opens dropped
directory or opens directory which contains dropped file and selects
it. I need just hit enter and this file opens. Same with save file
dialot.

Will be nice tho have this feature in blender.
