Things what annoys me on PSX for android

I can't use the same effect for more than one time - for example i want to turn down lights, but in lowest level it's still not enough and I want more. There is no button what saves my actual edit and let me use the same effect for second time.

Same with using (lights) covering. I have a picture where there are several light bulbs and I want to give each of them an extra equal beam of light to make it look like the light bulb is shining. No, I have to save the image like an i...t and open it again and again in psx 6x for each added ray separately. 

I would really like to get a button that saves the used effects/filters and any thinh and can use them multiple times during ONE editing. PicsArt can do this for 10 years!!!

Also since the PSX changed and is not available in the Samsung version, RAW photo editing (lights, shadows and other things) works worse and edits photos in a weird way than the 2020 version.

I also noticed a bug in the application - if I change the color shade of the raw photo by just one number, the whole photo changes and has different shades when I go the original value, an I must to click at step back button to be where I was before.

So if somebody can finally add/fix these, i would be happy!
