Feature request: repeat last script run

### Scenario:
1. edit file utils.js
2. edit file main.js (which requires utils.js)
3. Run application with Ctrl-Shift-B
4. further edit file utils.js
5. switch to main.js editor
6. Run application with Ctrl-Shift-B
### Problem / feature request:

I'd like to get rid of step 5. and still be able to execute main.js without leaving utils.js editor.
It would be handy to have some command to repeat the run of last executed script without opening it in editor.
