Installed and launched @KaleidoscopeApp (6.5, 9664) on my work Mac and was greeted by the welcome screen. Decided to add integrations and in the midst of configuring integrations the modal lost its title (there is no other close button and neither the escape key nor CMD+W worked).

So yeah it’s going great.

@macronaut sorry to hear about the troubles. What version of macOS are you on? Will try to reproduce the issue and follow-up. As for workaround: force -quit should be fine, the operation in the integration should be done.
@KaleidoscopeApp I am on macOS 15.7.3; yes I had to force quit the app to resolve the issue.
@macronaut managed to reproduce the issue, so will be fixed in the next update. Thx for reporting the problem!
