Just wanted to give some information about upcoming RSSOwl 1.1.1. The release aims to be a bugfix release with the exception that the ToolBar above the tree will be back in place. Thanks for all the feedback on this issue.
I am planning to release 1.1.1 directly after Milestone 7 of SWT, which is dated on middle of May. Currently the SWT Team is fixing a lot of bugs. Some of these are also very important for RSSOwl.
