@geneven: I've uploaded 0.5.2-2 in extras-devel which to try the proxy support. Can you give it a try and let me know if feeds update with your proxy? Images, and other side downloads might not work yet, just the feed updates.

@sorodoros: is it slow for all feeds? i've noticed some css and flash applets causes it to slow down quite a bit, but most pages are fairly smooth (not as smooth as it should/could be, but very usable).
Also, 0.5.2-2 now uses the theme color for unread messages.

Note, there is an issue in the 0.5 series with the read/unread tracking, sometimes articles are listed multiple times. Leaving the feed listing, and coming back in usually fixes it.
