A few simple questio about Gpt Plus

I have a Gpt Plus subscription and therefore have a number of questions
1).Can gpt plus write long messages and continue generating to the end by itself, bypassing the button press - continue generating?
2).Gpt plus also has restrictions to 4a is everyone like this?
3).Is there any way to get faster information from GPT plus. For example, the same code takes a very long time to generate and write. If you need to make a correction, you have to wait a very long time for it to finish.

Sorry for the stupid questions, hopefully you can give me some information
