> I decided early on to edit the menus to remove a lot of the "junk" and replace it with my list of apps, so I fired up the Main Menu Editor app. Normally this is quite responsive, but on the resource-challenged Zero it had worrying lags and pauses as changes were made. Ultimately, it meant that my ad-hoc menus were corrupted and worse still, the default Pi menus had been reinstated.
If I understand Raspian’s portability correctly, this could be mitigated by preparing the system disk on a Pi w/ more resources, e.g. a Pi3– run Main Menu Editor w/ system disk in Pi3, then put system disk in Pi Zero W when menus are edited to satisfaction.
