I have been trying to use a PicLayer plugin in the JOSM editor, however after installing the plugin it would never appear in the top menu next to Windows, Audio, Help dropdowns (at least that's where I think it should be). I must say I am a total newbie to JOSM, and I do have no idea on how to even uninstall that plugin, so i could give it another try installing it back (so it hopefully shows now). I'd appreciate any hints on how to uninstall that plugin, thanks.
P.S. the reason I came here as opposed to JOSM forums was because they, for some reason have shut down the registration.
