Here's a usability question that I'd like to get some feedback on. Myself, I'm undecided.
How to display and input values of opacity and blur?
- As percent, 0 to 100, or 0.0 to 100.0.
Pro: easier to pronounce; more common in "real life"; spinbutton can be shorter by one character (dot).
Contra: requires a "%" label after the spinbutton; if the label is not there (as e.g. in the statusbar there's little room for it), it may be more difficult to guess, when you see e.g. "15", that the maximum is 100; requires a change from the Inkscape status quo.
- As numbers from 0.0 to 1.0 (with two or three significant digits).
Pro: no need for a % label; easier to guess what the maximum is (though still not entirely obvious, unless you have a slider too); no need to change the status quo.
Contra: slightly more "geeky", more cumbersome to type and pronounce, requires slightly wider spinbutton.
Opinions?
I would personally vote for the second, which gives more consistent look in inkscape (eg. calligraphy options are in the 0.0 to 1.0 range).
Is it technically possible to allow the user type, let's say '75' and automatically transform this to '0.75'? That would make the typing as easy as the percentage option. This feature would also be helpful in all other 0-to-1 input controls.
