Currently if you try using some special characters in the PRESET names, SBA crashes and the preset is deleted.
But other special characters are acceptable.
The very frustrating part is that presets are deleted during the crash.
A suggestion is to have the user-interface check for characters which are not acceptable on the front end, and pop-up a warning to the user that those are not acceptable. A crash is okay but what should definitely not happen is to have the preset deleted.
As a temporary solution, just adding some text under the "Modify the preset name:" pop-up saying "only these special-chars are acceptable: x, y, z, etc." would be very useful.
