I would like to request autoscroll. Having found DT an excellent environment for writing, I would use it more for reading, too, if it had autoscroll. At present, I’m saving long documents as PDFs, then reading them in Acrobat Reader.
Could you explain what “autoscroll” means for you? Have you tried the various options in View > PDF Display?
By autoscroll, I mean a feature wherein the pane displaying a document (or window if the document is opened in a separate window) scrolls through the text with no further input from the user. Adobe Reader has this feature, and it is quite handy for long documents such as books, especially if you are a quick reader. The scrolling speed is adjustable, so each reader can set it wherever he/she wants.
