1. Remove attachments from email messages
2. A button editor
3. The ability to perform gestures over images, as we could in Opera 7.0
4. PGP/GPG and similar features for mail
5. Compressed web archives, and compressed mail storage.
As you can see, a couple of these go way back ...
Yes, in Opera 7.0 you could assigna gesture to Save image and it would act on the image you started the gesture over. For some reason, this feature simply disappeared in 7.10.
Back before most email providers had virus filters, I wanted the ability to remove an infected attachment from a message without actually removing the message. But I can also see that you might want to save an attachment to disk so you can view it - but if you've saved it, why do you still need it in the message?
I'd like a simple dialog that you could get when you right-click on a UI button so that you could edit that button. Obviously, it would be nice if you could graphically choose the button icon, but even something that's strictly text would be okay. Of course, the same button could be used to create a new button.
I don't think that PGP/GPG support really needs any explanation, but I'll say the obvious anyway: If someone sends you a message with a detached PGP signature, you should be able to verify the signature without having to copy the raw message and paste it into a file.
And finally ... HTML and email both take lots of memory. Many web servers will transmit web pages compressed (seems like UNIX z compression is the default) for just this reason. When you save a page - especially as a web archive - you should be able to save it compressed. And of course, Opera should read the file without some third-party unarchiver. Same applies to email storage, but more so since most people have lots more stored email then stored web pages.
I'm supposed to tag "up to 5" people ... I haven't made up my mind yet, but I'll find someone (and say who in a comment so you can see what they post).
Addendum: they tell me - now - that rules for this game require I list the people in my blog post.
Okay, I tagged philry4n, fammcdon, Sanguinemoon, and sebt.
