Aggregator v2.0
From now on Aggregator can crunch also Atom feeds! Starting with this release any feed (RSS/Atom) should be supported.
The most requested feature was finally added to Aggregator: import. Feeds can be imported from Google Reader OPML files and Aggregator's own OPML files. The import can be partial in that you can select what feeds will be imported. To make selection easier, one can invert the selection using the provided menu option.
Aggregator can now export its own feeds too. The export can be done to an existing file (*.xml or *.opml) or to a newly created file.
To make the application more appealing I also added the feed's icon to the title bar.
NOTE: With great power comes great responsibility. Importing feeds from Google Reader is a nice thing to have, but use it wisely! With each new feed which is updated regularly in the background, the phone's battery will last less.
