Text to Speech for the Viewer would be *amazing*!
I understand (and currently use) the "Open With ..." option and Balabolka as a decent work around. However, Balabolka doesn't remember where you left off in a given file *and* recently truncated the bookmarks hopping tools, so when your TOC is long it gets to be a right PITA finding where you left off listening. Not to mention it's a text-only environment so maps, figures, and illustrations require opening the book in the viewer anyway.
I did see the plugin threads for the dropped
[Viewer Plugin] Text to Speech and I have the
TTS to MP3 plug in. I *wish* the first hadn't been dropped because that's my target ideal. The second, while good, uses a lot more disk space and has similar problems to the Balabolka work around.
