I’ve released an update to my ZoomBySite Safari extension.
There are two main changes in this version:
A new setting has been added to provide a default zoom level. All web sites that do not have a specific zoom level set will zoom to the level specified in this setting.
ZoomBySite now works on Gmail (at least on mail.google.com). Unfortunately, I haven’t solved the greater problem of working with all sites with iframes, but I have provided a solution specifically for Gmail.
As always, ZoomBySite is available for download from my site.
