No accessibility issues what soever
The app is fully accessible with VoiceOver and is easy to navigate and use.
This app really just does what it says. It just came in very useful when I upgraded Teamtalk to a newer beta which isn't all that stable with Voiceover at the moment, and the old version wouldn't install even though I deleted the new version as well as the preferences. After running uninstallPKG and letting it do the work, I was successfully able to downgrade.
