Fetching News UI
I don't see any improvement in this area since I've been using Calibre for a few years now. Not sure if this is the right place to make suggestions, I'm not much of a programmer, otherwise, I'd try to contribute.
I would like to set a few news sources as "favorites" so that I can download them manually with one click of a button. The only way I can do that now is to set a source as a scheduled download, and simply uncheck all the days so that it doesn't download automatically, but only when I want to.
I would imagine that this could be improved, simply putting a check next to a source to make it a favorite, maybe have a few different categories, like "daily", "monthly", even user specified labels.
And going through the process just now of setting a source as scheduled, I see another user interface problem: I have to press "Save", otherwise, if I click on another source, and go back again, my changes are lost.
However, pressing "Save" -- although saving my preference as designed -- throws me back to the main screen, and I have to navigate all over again to my source, which, for English sources, means wading through a lot of dropdowns and lists.
Perhaps there could be an "Apply" button which would keep me on the same selected news source, so that I can make similar changes to other sources without starting over.
Hope these suggestions make sense to someone. They're pretty obvious to me as a user of calibre for reading news on my eReader.
