Menu should say 'Loading...' while loading

[jnphilipp]

While using the indicator I came across a few thing which would be nice to have.

First: While loading the new feedlist the menu freezes. You need to wait until it finishes loading. It would be nice that the menu say 'Loading...' while loading or something like it.

Second: Currently a post is in the list as long it is in the feed, it would be nice if it will be longer in the list. I've feed with just 10 post but an output of 20 or more per day. I thought about a simple database to save the parsed feeds or and additional list for unread feeds and a corresponding cache file.

I hadn't a good idea for these features and i would be glad about some input.
