Improve navigation from source code to test

[criemen]

Is your feature request related to a problem? Please describe.
I find myself using the CLI test runner, as navigating in the test ui to the test I am working on is quite a hassle, it is too slow.

Describe the solution you'd like
Some way to
a1) jump from a source code that is test file to the test runner
a2) Have an auto-navigation mode from active file to the test tree (like in the file system view, where an open editor immediately opens the tree and selects the currently opened file)
b) A button exectute tests immediately from the file system view, like the "Run Query" command
