If you'd like to test Omnivore before the official 1.0 release, this is it! See the 1.0 milestone for the list of bugs targeted and fixed for this release.
I plan on a more complete set of documentation for the 1.0 release, but at least there is some documentation now at Help -> User Guide
MS Windows Note: Omnivore is now packaged as a single executable, not an installer. This executable can be run from anywhere, and doesn't need administrator privileges. Please uninstall previous versions so there isn't confusion about which version to run, because existing links on the desktop or pinned in the task bar will point to the old version.
