General questions on Wrappler on app, data and usage

Hi there,
I am new to Wrappler (I don’t even have it yet), and before I dive in, I’d like to ask some things I didn’t find in the docs:

Is it possible to:

• use Framework7 (instead of Bootstrap) to create a desktop/browser site (target is desktop, fallback is mobile)?
• use Framework7 Vue inside Wappler? (I mostly communicate with my Frontend using JSON and the Vue reactive components are awesome for that).
• use SQLite as data-provider in a webapp? (How would that work in Cordova?)
• use JSON as data-provider? (and can I add items to the JSON)?
• connnect a Wordpress backend to a Wappler-created site and pull data from there (e.g. using their REST-API)?
  • if yes: can I pull Wordpress-data and save that locally (including images), so I can build a PWA from it? (or bundle them in my app)?

As far as app-bundling (for hybrid apps, e.g. Cordova) is concerned:

• Is the generated code/structure compatible with Microsoft’s CodePush service?
• How are (native Cordova-) plugins handled within Wappler?
• Can I use Fastlane in the project?

Is there a description somewhere what all these extensions listed on the ‘Buy now’ page are (and are good for)?

TIA - and sorry for the lengthy post.
