At the moment you have to press capture > Click on the timestamp > Press the space bar to insert a space and then start typing > Then click save

It would be better if when you press Capture it would allow you to start typing straight away and then press enter to Save

Hi, RandmTask. the extension features of vlc are very limited, the input box cannot be automatically activated and the shortcut keys are not supported.
