Make it Portable

[amymor]

First of all, thank you for such a great app.
By "portable" I mean store all settings in the app folder, not in AppData or Registry. In this way, if you reinstall Windows, you don't have to worry about backing up the settings. The application can also be executed from flash drives on other machines, offering flexibility. Another use is that if the Windows disk fails, the app and its settings will remain intact if they are located on a separate disk. Windows disk is more likely to fail due to its high read/write frequency, as evidenced by my brother's recent Samsung SSD failure.

Mode which would include change

• Full-screen Grab
• Grab Frame
• Edit Text Window
• Quick Simple Lookup
• Settings Window
• General
