as the blog discussion was closed for further comments, I would like to voice my desire for a ND filter and dehaze.
Recently a friend of mine who uses Raw Therapee on Linux saw Raw Power on my Mac, and while Raw Therapee is really a super powerful and versatile package, he was impressed with the simplicity of the UI of Raw Power. So while we continue to ask for additions to the Raw Power feature set, a priority should be to maintain the clean UI of it, so to avoid a convoluted UI as you see it in Raw Therapee.
Indeed, fully agree that this is paramount yet a challenge.
Being able to customize the UI by hiding/revealing functional sections and modifying their sort order would be fantastic. RT with its vast range of features arranged in different tabs, each plagued with lots of scrolling, is not a reference. In all fairness, I have not explored the possibilities of customizing its UI.
