Thanks for the compliments. Just so you know, the entire development team is just me.
Sort, Filter and Select are in the toolbar (this is similar to photos). In general, interface elements appear above the item they affect. The quick filter and the file name filter are part of the grid and thus appear above it. When you tap to view an image, the quick filter and file name move down, because the grid turns into a film strip. Sort, Filter and Select are in the spot that people expect them to be. Quick Filter and File Name filter are advanced features.
As far Sort and Filter, etc. appearing when you are editing, you can indeed select, sort and filter at that point. Remember, Sort, select, and filter affect the current album or folder. They do not filter the library.
If you are suggesting that Help should be moved into a menu, I disagree. Help needs to be a top level item because it’s for people who aren’t familiar with the app.
AI Eraser – I do not follow what you are saying about back and forth.
Bold text for titles – that will look awful when all of the blocks are closed. I will think about adjusting font sizes though.
Split Toning circles – yes, that might help but I don’t know if people would expect that making a panel wider would also make an adjustment taller.
What is an “Accent Color Picker”?
There are some known bugs with masking and perspective. Crop, by itself, works properly with masking, I believe.
Being able to hide adjustments is on the list to do. But it will require a way for people to then add adjustments that are hidden, which has to go somewhere, and there isn’t a good spot for that right now.
Geometric operations on masks is most definitely not “universal.” I can see the value of it though but it’s non-trivial. Any mask can be brushed or erased which means that the operations are not simple geometry.
Versions is on the to do list. You can look at the roadmap on the Nitro web page to see more items (though it’s not exhaustive)
