I’ve been using the subtitle feature a lot lately and I realised one time consuming thing I do very often is to resize the current subtitle line to the length of the clip below it. Currently adding a new line seems to default to a 2 second subtitle length (which I personally think should be 3 seconds, but it depends a lot on the type of video) so I have to resize it after every single new line.
I think either a keyboard shortcut (which would change an existing line) or a new checkmark in the subtitle panel’s options to default new lines to the length of the clip directly below it would be very helpful.
