Fix the defaults
People rarely go into preferences and change the defaults. So for them it’s important to have good default values from the start. For people who know how to change the defaults it’s helpful if those defaults start out with the right values.
I’m talking about the font size and leading increments and kerning/tracking value increments. Why would the default increment be two points for font size and leading, not one? Does Adobe think we want to make it faster to greatly increase the point size at the expense of not being able to dial in the exact point size size we need? The same with leading. If I’m trying to adjust leading with keyboard shortcuts I want to at least have the ability to get the exact point I want. Two points is obviously the wrong increment, and it has been for over a decade.
Kerning and tracking are probably not adjusted by most users. For those of us that do we want a finer increment than twenty units. Five is the correct value here.
Please, save us professionals the trouble of changing the defaults by setting them properly from the start.
Oh, and these preferences should be application wide preferences, not document preferences. When I use the shortcut I expect consistent behaviour. If I increase the point size by two presses of the shortcut I expect to increase point size by two points. If I use the same shortcut on the same computer using the same version of InDesign but on a document created by another designer the shortcut might behave differently. Why would I want that to happen? The preferences for keyboard increment shouldn’t be saved with the document, they should be an application preference.
