Thank you that you have the ability to move ScreenToGif window! But I think it would be very nice if users could ScreenToGif resize recordable area of ​​the screen during recording.
When the screen recording is not started, I can change the screen size.

But when screen recording is already started, I can not change the screen size.

Thanks.
I did this on purpose to prevent a recording with different sizes.
To enable this, first I'll need to enable some flexibility on my code, I believe it can be done,
