I love that the function button is programmable. It would be awesome if a second option could be added for a long press.
Someone mentioned adding a manual/auto setting toggle for the fn button. I would like to use this for the single press and toggle the flash for the long press.
Good idea, we will add long press to the FN button in the big update.
We have added long press to toggle between Auto <-> Manual mode in our recent 1.4.2 update.
We haven’t added a setting for long press (yet?), we might do that in a later release.
Long press should be able to have the same options that single click does. While you’re at it a double click option would add even more flexibility.
