FARR should run fine on any resolution, though as with all of my apps, the options dialog may have small fonts.
As for right click menu item, you mean add a menu item to your windows explorer file browser to add an item to FARR?
There is already a right-click add alias item in farr itself, so if you search for an item in far (or use directory browsing option in farr), you can right-click to add an alias for it.
