I think e.foundation should swap to simple mobile tools https://simplemobiletools.com/
because the default apps for calendar, contacts, gallery and so an doesn’t have all needed options and every apps does have his own screen layout. All simple apps does have the same screen layout, a lot of features and they are simle to use. And for mom and dads and grannys it would be easier when each app does have the same screen layout.
I once setup a ROM where I replaced all the default apps with their Simple Mobile Tools equivalents. It worked out pretty well except for Calendar. Calendar doesn’t (or didn’t at the time) display events that went over midnight. I work at night so that was a crucial need. The dev told me it was by design. Not good so I went with Etar instead. That one omission broke my all-SMT environment I wanted. Don’t know if things have changed since then.
But anyway I think it’s a nice idea to use SMT. I think there’s about a dozen apps in the collection which are all capable.
The apps are good but I’d stick to Open Camera, Musicolet, and Amaze for the Camera, Music Player, and File Manager Apps respectively as those 3 apps have way more features and at least the first and third ones are open-source (at least Musicolet only asks for file permissions; no internet permissions = no ads).
I use SMT as much as possible since a long time and didn’t encounter any issue. But I have the privilege to be able to sleep overnight, therefore the calendar app issue described by marcdw doesn’t affect me. Btw.: I just tried, it’s still an issue.
Nevertheless I would strongly recommend to use SMT as default apps, as they just do what they should and the UI is consistent and easy to use. That perfectly fits with the philosophy of /e/.
