[FEATURE] Save & Close Current Tab + ability to not open Tab Space after saving.

[HighTML]

Is your feature request related to a problem? Please describe.
I'm always "frustrated" when I want to save a tab to a specific location because I want to close it and continue on something else. Right now I click "Save Current Tab", and then I need to close the Tab Space and then also close the current tab when I am back. Would be nice to do it all in one go.

Describe the solutions you'd like

1. Add the option "Save & Close Current Tab" which does what it says.
2. Have a setting "Always open Tab Space after saving", which defaults to true. True is the current behaviour. It would be nice to not always open the Tab Space, so you can just save and close a tab and continue without needing to close Tab Space manually.

Keep up the good work, I love Tab Space 👍
