please give us gamma 1 for blending even without the need to trick around with layers.

Hello! 
I am a very happy convert from Photoshop to Affinity except for one thing: the brush tool settings. Photoshop still is a lot better with these because of their more sophisticated brush tool modification options. I am thinking specifically about dual brush, brush pose, and build up, which don't seem to be available in Affinity photo. 
I recently bought a set of .abr brushes to compare and contrast the import success between Photoshop and AP, and I'm sorry to say that while Photoshop was able to accommodate some really nice subtle effects (I just want a nice, natural inking brush. There are a million great "big wash" brushes for affinity, but I can't find good liners for the life of me!) that were set into the .abr files, but Affinity imported them as regular round brushes with a noise texture on them, which looked awful! 
I would really like:
1. to be given some actually helpful tutorials on how to create natural-looking brushes in Affinity (I've had a heck of a time trying to find what I'm looking for. People make tutorials for really silly, goofy brushes, but nothing really practical for fine art!)
2. For the Affinity brush settings to be upgraded to be more competitive with the Photoshop brush settings. 
3. For AP to be able to import .abr brushes properly without cutting out the settings and ruining the brush. 
Thanks for hearing me out! Again, I am LOVING the program for the most part, but I'm just not able to do inking on this program to the level that I want, because of these settings issues.

Same problem for me. Very frustrating when you used to work quickly with healing brush/tool and press alt/option to pick color and it stay on the last pick, not the new one you just referred. £Never had this problem with Photoshop.
Please fix this, thank you.

In Affinity Photo, Color Picker is extremely slow. It's terrible. When you use Brush tool and press alt/option to pick color, Color picker work so slow that it causes a lot of anger. please make your Color picker tool quick. Better fast and uptime than beauty.

Watch both links. Gimp v2.10.28 gamma is perfect, Pass my test.
this modification to give more space to darker values does lead to wonky color maths when mixing the colors.
We can see this with the following experiment:

Left: Colored circles blurred in a regular sRGB space. Right: Colored circles blurred in a linear space.
Colored circles, half blurred. In a gamma-corrected environment, this gives an odd black border. In a linear environment, this gives us a nice gradation.
This also counts for color smudge brush:

That’s right, the ‘muddying’ of colors as is a common complaint by digital painters everywhere, is in fact, a gamma-corrected colorspace mucking up your colors. If you had been working in LAB to avoid this, be sure to try out a linear rgb color space.
