Most of my pix require a Watermark. It would be real nice for there to be a tab, shortcut or something in Lighttable that I can select an image and Watermark it then export. For example I may have 30 images to be exported. 10 need the Watermark on the top right corner. I can select those 10 then add the Watermark. Then I can select all the images that require a watermark on bottom left and do the same etc. Right now I have to select an image, open it in Darktable, add Watermark. Go back to Lighttable and export.
Make a style out of your watermark. Having one random module detached from pixelpipe to export module will backfire badly and exceptions like this are precisely what I want to avoid.
