how do you lock layer alpha?

[blurymind]

According to your website, you can:
https://www.artrage.com/artrage-android/features/
Independent Layer Locks allow you to lock transparency.

So where is the lock? I dont see it!

Also how do you export png with a transparent bg, how does one set the bg to be transparent?
How do you save the artrage file with the layers and edit it on your desktop?

You havent made it very obvious

Apart of that I have to say that I am quite pleased with my purchase.

PS: Also there is no Sticker tool -

The image that you are using is misleading the artrage studio user to believe that the android version has it too.
why is the android features page promoting non existent features?
