RetroArch Navigation Woes

Small rant: So I just updated to RA 1.9.0 on PSC. Of course User 1 had the PSC controller. But I wanted to use my wired Switch gamepad, which was User 2. So I switched the gamepad for User 1 to the Switch pad … and then neither gamepad could control the menu. And I forgot to disable the option to automatically save configuration after the update. The feature to allow all users to control the menu was removed in between 1.8.5 and 1.9.0 too. I thought I’d have to find someone with a PC to delete my config file (deleting files: another missing feature, which I use DOS tools to work around). But my keyboards finally worked (except certain keys) and allowed me to navigate and configure the pads. Phew.
