I found a really little thing, which I noticed a few times during work and was a little disturbed by it.
Normally I can open the sorter and by clicking outside the sorter it closes again. But this is only not the case if I have selected the Capture function for Safari and leave it again directly. The window always stays open until I click the icon in the menu bar.
The second thing is that when I want to capture a text note and leave the sorter while the last word has a non applied / declined proposal for spelling, I am not able to get the focus back to the sorter window to continue writing. I can move around the text courser in the sorter text field with the mouse but every keyboard input is being applied somewhere else to the previous used app.
