I sometimes manage more than one instance of B4A. There fore, every time you open a different project, you have to locate en keystore file each time. It would be great that the META info from the project could store the location of the keystore, so when it opens, it points directly to the keystore file.
Usually you only set the keystore ONE TIME (for you as the developer). No need to change it between projects.
I am using the same Keystore since 2013 in all my Projects.
