Show live values on the mockup, blink a screen to identify it, try an alert, copy and share layouts (0.2.74)

The tiles draw what Home Assistant reports (a new /api/states answers for the tiles on the page); the ···
menu gets Identify (the screen's own show_alert with flash), Copy layout from another screen, Export and
Import as JSON; the Alerts page opens with Try it (/api/alerts/test, one screen or all); the library filters
by room and hides what is placed, with lit icons for what is on; ⌘K searches screens, entities and actions;
the Update badge lists what's new from the changelog (copied into the image) and a running update shows a
progress bar with the ESPHome stage and the last log line.
