Continuously add shapes while using the brush tool
When using the brush tool in drawing masks, e.g. in the exposure module, the workflow could be improved by automatically add a new shape until the users deactivates it by clicking on the brush icon in the menu. Similar to feature #12038 this would help the user to focus more on the images while adding new brush strokes. Currently your eyes are switching constantly between the module and the image while adding a new shape.
