Reopen last file on startup
When ticked, the app automatically reopens whichever file you had open last, the next time you start it. Off by default.
Default folder for your table style (.ksstyle) files
Sets the folder the Export and Import dialogs start in, so you don't have to navigate to your usual style-file location every time. See Portable style files (.ksstyle) for how Export/Import work.
