Feature request for "Import plain text"

[darnn]

Hi. Fairly often I find myself in a situation where I'm importing dialogue from a script. Usually this means that a lot of lines are fairly short, but there are occasionally long monologues and so on. If a lot of short lines are something like:
Okay. Fine. We'll go. Now.
I don't want to split that up into four subtitles. However, I do want to split the longer chunks of text so that they wouldn't exceed the line length, but with the sentence structure in the chunks intact as well. To that end, I propose an additional setting, alongside Split at end chars - something like Split at end chars only when exceeding max line length.
So if you have the text:
Good night and thank you. Yes. We are grateful for your contribution.
The length of which is 69, and you've set the number of lines to 1 and the single line max length to 60, you'd get
Good night and thank you. Yes.
in one subtitle, and then
We are grateful for your contribution.
in the next.
