Keep Sketch Window in Background

[fabb]

On every save the Sketch window gets active, while the editor loses focus.

Expected behavior:

Would be nice if the focus would stay in the text editor, also after saving.

Observed behavior:

On every save in the text editor, the re-rendering happens, and the Sketch window becomes active.

How to reproduce:

Save.

Sketch version:

43.2
