In general my first impressions with the resizable cards in sections view is that it’s nice, but it’s less flexible than I hoped it would be. For example, there are barely any cards that can be 1 cell wide. So setting any card to be 3 cell wide doesn’t make sense in almost any case, limiting the practical options to 2 cells or 4 cells wide.
Some things in the grid were placed in a way to make it look nice, to follow the lines of the grid. But not everything. I’m not a fan of how the tile cards look with one or more bars, as there is an unnecessary big white space below the icon and name, and the bars do not fit the grid at all, they don’t even fit nicely with other tile cards:
So in this case the flexibility is quite limited and still the neat look is not achieved.
Another example is the glances card. If you set it to only show icons, the icons are fit to grid in height, but not in width. While this is limiting flexibility (as there’s no way to for example fit 5 rows of icons in 4 rows of the grid), it does look nice (although would be better if each row was center aligned in height, like the text in the tile card, not bottom aligned):
However, if you also try to display names and/or statuses, the fit to grid aspect is lost completely. For example 3 lines of icons and names take 4 grid rows:
and with statuses also enabled they take 5 grid rows.
Overall I do like the change, it makes it easier to do some things, especially to make tile cards that are whole-section wide without tricks.
Of course the elephant in the room is still that the older cards look so completely different compared to the tile card, they use different color scheme, mark unavailable entities differently etc. I would love to know what’s the direction HA will take about this. Are the older cards going to get some love?
