Hello Admin I found the In Built Keystore is very helpful and easy to use. So I am very okay with the old version v3.0.2 Pro.
But some updates are not in this version, so I had to use the latest release even I don't like the Custom Keystore feature.
So I would request to keep an option in future edit, where user can use or may have option to use the "In Built Keystore" for all his apps or if someone needs "custom keystore" he can use the custom keystore option.
I hope you understand my massage. What I suggest is to keep an option for using In Built Keystore in keywords menu. So every time we don't need to click that menu.
