I use this for closed captions on my live streams that are cross-streamed to both Twitch and YouTube. This tool is invaluable as pretty much every other caption tool either requires a Chromium browser (I use Firefox) or only works on Twitch.
As such, I'm always capturing this window every stream and I would like the ability to add a stoke to the text to make it easier to read without having to put a background that will cover more screen space. Additionally the option to have the text be set to a certain % of the windows rather than using the entire length would be great for when I'm cropping out the close button in OBS (i.e. a setting to always have the right-most 10% of the windows never show any part of the text, giving me a buffer area to crop in without worrying about cropping any of the text itself)
