Hi Bertrand,
Interestingly everybody wants to make a tool for the ‘none-technical’ people, although I think there is plenty of room to create a tool for ‘technical’ people as well 
I really like your choice of tools, starting with MacOSX 64bit, SQLite, etc… I for one, would appreciate a syncing option (e.g. iCloud or Dropbox or whatever), because - at least in my life - it happens (quite often) that I change machines multiple times a day. Having my sync in place helps me a lot to get work done without further thinking about keeping everything in sync.
Even more: Right now a cool editor software on the iPad is missing completely (I guess, mostly because of sandboxing issues, etc…). Having such a tool on the iPad would be awesome, especially if it comes to work as a ‘Digital nomad’.
As you already mentioned: Templates are a big benefit (especially, if they can be customized and re-used).
This would be especially true, if the app generates needed assets as well (info.plist, app-icons, application icons, splash-screen), much like XCode does.
And as Vladimir already mentioned: Cordova and/or Capacitor integration (especially the latter in combination with F7 is a black hole right now)
Database Implementation: You mentioned ‘Infinite Scrolling’, etc… You didn’t mention ‘Virtual Lists/Slides’: Maybe you already have that in the works, but this one is (after Infinite Scrolling - or even before), one of the most significant concepts in F7! (I love it: thanks Vladimir for that!)
Language: if you need some help localize to german or italian, just drop me a note.
GoogleMaps API: After the recent policy change of GoogleMaps, I completely abandonned GoogleMaps for all of my projects, as this is a completely insane step for developers (I DO understand Google, but for me it’s a no-go). I am currently switching some stuff over to OpenStreetMap and the wonderful Leaflet.js implementation, which are more than enough for most projects.
I appreciate your effort pretty much, because I am just starting my first F7 project;
I played with F7 a lot in the past, but for most projects it was strictly too complicated to port them over. Most of the time there were working implementations using other frameworks already in place. AND in contrary to e.g. ionic, there are only very, very few templates and tools available for F7. (Additionally the framework switched very fast from v1 to v2 and now v3 ; both upgrades with breaking changes, which is not helpful when trying to launch a fresh project ;))
So I’m looking forward what you come up with.
Pricing is absolutely okay for me.
This reply is already a bit too long (sorry for that), but if you need some more/detailed feedback, just drop me a note.
