Hi Arthur,
yes, you are right, I have done changes for Ext in another branch, and forgot to integrate them. Would be added next beta.
With titles... Generally it is same dialog, but with different filters. That is why names are equal. But I can change them.
With click on title. It is a bug, it just executes top-left item. Would be fixed.
Thanks for a bug report.
Best regards,
Alex.
