[Feature] Provide configuration for floating terminal title

[protiumx]

Hi, thanks for the awesome plugin! I didn't find any way to configure the title in a floating terminal. I'd like to avoid trimming to see the whole command and also change colors.

I'd also like to be able to customize the color. The rainbow coloring can make it a bit difficult to read depending on the editor color scheme.

There is a refact PR I am working on blocking title updates. Will back to this once that one resolved

ray-x, I'm using navigator plugin. How to disable this rainbow title and make it as usual?
