Hi,

VERY good ! I was talking about general buttons handling (plustek uses
integer).

title and desc are translatable, so it make it impossible for frontend
to handle in a generic manner. Since backend only rely on option index,
it's just plain useless to use button%d (some backend uses button-%d
through). Since this is quite a mess for buttons naming, i guess you
should not base your naming on this ;)

>       - printer button
>       - '+' button
>       - '-' button
>       - toggle color/gray scan mode button
>       - spanner button
>       - red triangle within a red circle button

very very interesting, especially "scan","www","mail","printer",etc.
Having a set a well known buttons would help so much to provide smart
button handling on high level. Prodividing extended meaning in title,
desc and man pages will help handling such button in frontend.
