Disabling auto-refresh both per feed or globally

[amirsol81]

It seems to me that Raven Reader doesn't allow us to disable auto-refreshing feeds altogether. It has settings for 1-minute, 5-minute, 60-minute, etc auto-refreshes, but auto-refreshing can't be disabled in the Settings window at all. Upon start-up, I'd like to be able to manually refresh some feeds and ignore many others, but currently the app refreshes all feeds at start-up. Moreover, I don't want certain feeds to be auto-refreshed at all - especially certain news feeds.
And, last but not least, it would be quite useful to also be able to set auto-refresh periods either per feed or per category, or disable it for them altogether. That way, certain feeds, or categories, can be auto-refreshed faster, some can be auto-refreshed with longer delays, and auto-refreshing can be disabled for some feeds altogether.
It's worth mentioning that almost all modern RSS readers have such settings, so please also kindly consider adding these relevant settings to Raven Reader.
