Great work @Ionut, just bought Ariela PRO to show some support 
As I already switched to lovelace, I’m having trouble reconstructing my lovelace view to Ariela.
I’m using custom-button card, it isn’t supported by Ariela, but I’m willing to switch to core button card, that is supported (I think).
Now the trouble is that I cannot get the same result as I get with web view.
I use vertical-horizontal stack to define the row for the buttons, but when I was testing the new lovelace layout, web view looked like it suppose to, but in ariela all button cards was arranged one by one.
I treyed with column number, but that didn’t gave great results.
Anyone else using button card, would love some examples that work with Ariela, and still look good in web view?
Here is a sample of my web view (don’t mind custom button card and modder, I can live without that), is something like that possible to achieve in Ariela?
Also is simple-thermostat supported in Ariela?
