[Feature] Navigation, Color, Entities on Screensaver

[onyxkyr]

Hello,

I had the opportunity to test out your native lovelace approach - I am really loving it, the responsiveness is amazing and makes the NSPanels much easier to interact with. I have six NSPanels installed currently running the appdaemon version, and for me a couple of features are missing before I can move all panels to the native port.
I added two images from the appdaemon version to highlight the following features:

• Screensaver entities
  On the bottom right, instead of a weather forecast I have a forecast for the next waste collection, for which I included a custom entity which features waste type as name and corresponding icon.
• Entity color
  Expanding on that, the icon is colored depending on how many days remain to the next recycling cycle.

To realise this natively, I would just need to be able to add entities to the screensaver and set their color.

• Navigation entities
  In order to control multiple rooms, I set up custom navigation for which I require the navigations in the top right and left corner of the screen (the little house and checkmark, respectively). Being able to set these up would enable easy navigation between different screens.
• Display timer
  The appdaemon port features a time for the display. Since we can already toggle the screen via esphome, this would just be nice to have.

I am a little busy in the next weeks, but can also look into helping realise these feature thereafter - haven't found the time to test the new upload mentioned in #20 yet.

Thanks for all your effort!

I read this issue but forgot to reply, sorry! I'm glad you like it, thanks for testing it out!
I think these features are possible to add but they will take time to develop as they are not simple additions unfortunately.

• Screensaver entities: Similar to [Feature] Screensaver Entities and Locales #22.. This will be possible but the screensaver code needs refactoring so the weather entity can be swapped for other entities. All the weather update code is in the main controller and needs moving but it isn't going to be simple because it needs to be efficient.. A large JSON object with weather information needs to be processed and should update all 'weather' entities based on their location on the screensaver, but weather entities could appear on other cards too so that scenario will also need considering when redesigning the code.
• Entity colors: I have looked in to adding custom color 'maps' before but I needed to think more about the design so it works for a range of configuration options. One thing that might never be possible is the ability to create custom state 'templates' because it requires using HA templating features which are not possible to evaluate on the device.
• Navigation entities: I have written some code to customise the status_icon_left/status_icon_right configuration options for the screensaver, so similar changes would need to be made to the appropriate cards in the code and python build script. Pop-up pages might be a little harder because they don't use the 'page' structure (this also needs refactoring when I have the time).
