Any news about clear history without close/open the file?

Clear history would still be really nice though, as it would allow clearing the history from memory whilst working on a doc to help performance.

On the Affinity Photo Feature List web page, in the Compatibility and Printing section, "TGA" appears on the Full Open or Import List. Perhaps there should be a parenthetical note included that says "(alpha channels are not supported)," similar to the notes for the AI & Freehand entries?

This is kind of a joke that this feature doesn't exist in an image editing software. Forget about the field you use your images, image files have channel information and that's all, in fact, we are editing. The fact that you can edit all the channels but Alpha makes no sense. There are countless uses of this in many different fields.
 
I've been trying to deliver my diploma project and really needed this feature. Despite having recommended to many people over around 2-3 years I'm using AP, I started considering quitting it altogether. It has too many down sides at this point. The excuses here are always like "Hey I never said this is a car, it just looks like a car but you can't drive it. Our audience is not drivers."

The greyscale values are just a single list of values.
A "greyscale LAYER" includes the greyscale list of values and a n opacity list of values.
All layers include an additional list of values for the opacity.
So, a greyscale LAYER is simple a set of two "greyscale" lists.
And an RGB LAYER is a set of four greyscale lists, one for Red, one for Green, one for Blue and one for opacity.
Once again, there is no excuse for the opacity list (call it alpha, or key, or mask, or opacity map, or whatever) that is merely a list of values just like a greyscale image or any of the composite channels of an RGB or CMYK image, to be treated differently.
In a nutshell, an alpha channel is exactly the same as a greyscale image and should be treated the same way, allowing all tools and operation that a greyscale image allows.

It sounds like you might not need training about Affinity, but rather about photography in general (composition, lighting, what makes a good photo vs a bad photo, etc.) which is something you need to know regardless of the tool(s) you choose to use.

Hi villain,
Welcome to Affinity Forums :)
As long as you are the only one using the software for commercial purposes, there's no issues. Just uninstall the software from the computer.
Here's the link for the full End User License Agreement (EULA).

Actually on that note, since we're dealing with high bit depth images, would it also be possible to have the levels controls and other similar features use floating point units? At the minute the range is from 0 to 100% in increments of "1" which of course isn't as accurate as we'd like :)
