[Usability] Zoom control

[Reinout van Schouwen <reinouts gnome org>]

Hello all,

On the Eye Of GNOME roadmap (http://live.gnome.org/EyeOfGnome) I saw a 
mention of the zoom control. The idea is to make it similar to evince.

Within the Epiphany project, we have been discussing changing the zoom 
widget to be more like the nautilus browsermode zoom widget 
(http://bugzilla.gnome.org/show_bug.cgi?id=117923). It's also an issue 
in the "porting" of Galeon to Epiphany 
(http://live.gnome.org/Epiphany_2fGaleonIssues)

However, to give the user a consistent experience, we would like to keep 
pace with other zoom controls like in Evince. To me it seems a 
discussion is desired about whether a (new) unified zoom control in 
GNOME is desired and what it should look like.

Allow me to do a proposal of my own:

(+) [units] (-)

This layout is similar to the nautilus zoom widget. Evince already 
allows configuring the toolbar widgets like this. Open questions: should 
this be a unified widget or should these be three separate widgets; and: 
should there be guidelines about when to use percentage values (100%) 
and when to use descriptions? ("Page width")

For webpages in particular I feel that percentage values are meaningless 
and we'd be better off with descriptions like 'Small' or 'Extra large'.

regards,
