I just want to add my voice to the list of folks that really look forward to this coming back - obviously opt-in and with the rough edges filed down. The scroll to zoom is much more natural to me for this type of application, and the zoom to cursor has been sorely needed for ages. Personally, I liked the scroll bars being removed, but I can see both sides of the argument for that. I'd never use the toolbar for zooming if I could use the scroll bar, so I have no opinion of the changes made there. Basically, the release was buggy and poorly rolled out, but I think that the hate was from one of two camps - a vocal group of people that genuinely hated it for varied reasons (possibly even a minority following the rule of unhappy people being much more likely to speak up than satisfied people), and those that probably liked the change on paper, but took (understandable) umbrage at the buggyness of the implementation. So, as others have suggested, make it opt-in when you do release it again, leaving the current functionality unmolested for those that don't opt-in, but please don't drop the idea based on the feedback provided in this thread. I'm glad their voices were heard, and their complaints were mostly valid, and the roll back was definitely the right choice here, but I just want it to be understood that there is certainly a significant part of your audience that liked the general direction of the change. Now, are there more important changes that should take precedence over these? Probably, but since the work is mostly done for this one, you may as well fix it up and do it correctly now before the code accumulates too much drift due to other features being implemented that it may have to account for.
