1. The keyboard shortcuts would work OK if I was a left handed mouse user, but... I'm right handed, so the keyboard shortcuts and mouse are both right hand operations, forcing me to move my hand between the two, or cross over awkwardly. The main gotcha for me is being able to scroll through the source images with the PageUp/PageDn keys. I can't do it comfortably without taking my hand off the mouse in Helicon. Since this is a frequent operation, it is quite inefficient. In Zerene, more functionality is given to the mouse, with modification by the shift and 'S' key. This is great for right handed use, because you don't have to take your hand off either mouse or keyboard during the retouch process. Specifically, Zerene maps this way during retouch:
- Scroll wheel with no modifier: sets brush size
Scroll wheel with Shift key: scrolls through stack for source image
Scroll wheel with Space bar: zoom in/out
S: show current source frame instead of destination (maybe less useful since Helicon previews source inside the brush)
Scroll wheel with S and Shift: show source as you scroll through stack
If you could allow remapping of the keyboard/mouse shortcuts like many apps do, that would probably be the easiest way to make it easier for Zerene people to migrate to Helicon. This would reduce the re-learning curve significantly and would allow both people who are right and left handed to work more naturally.
3. Retouch mode uses less than half of the screen to show the retouching image. My main monitor is 30" and it I'm still finding the image to be frustratingly small. I agree that it is nice to have the source image avaiable to see, but for me, it is better to see the destination image as large as possible. Ideally, Helicon would allow use of a second monitor for the source image and/or other UI, but this doesn't seem possible right now, and I expect it would be a significant development task. If that is a no-go, can you give a way to allow full screen or most of the screen for the image and give a keystroke to shift between source and destination as Zerene does?
I'm not saying you should duplicate Zerene, but they are doing some things right that would be a benefit to your users (well, me anyway.)
I do intend to purchase a license when my free period expires since I really like the direction you have taken with this product!
