It would be great if there was a way to select multiple objects objects and take action on them in bulk. This would be very useful for deleting multiple devices or apps (child apps), but would also be very handy for editing similar objects. For example, if I select 5 devices, the UI could show me only the knobs and dials which are common to all of those devices, and let me set them all in one swoop.
I could have used both a bulk edit and bulk delete functionality just tonight.
I had a handful of virtual presence devices that I wanted to switch to a different driver. Including a couple of click&drags to scroll the page and the driver selection box, I count a minimum of 7 clicks and 2 page loads per device driver changed. A bulk edit function could let me edit 5 devices in about 12 clicks and 2 page loads, instead of 35 clicks and 10 page loads.
After that, I needed to do some device cleanup, having recently moved a bunch of zigbee bulbs over to a secondary hub. I had 9 bulbs that were listed twice, once for the new virtual device sync'd from hub 2, and once for the original when the bulb was paired with hub 1. 5 clicks and 2 page loads to delete each bulb may not seem like much, but multiply those by 9 and it gets a little old. With a bulk delete, I envision clicking once to enter bulk mode, click once on a checkbox next to each device to be deleted, once on a delete button, and once more to confirm. 9 devices deleted in just 12 clicks, instead of 45!
I'm sure this would not be trivial to implement, and is probably not a high priority for the hubitat team right now, but I wanted to at least throw it out there for discussion and get it on the radar as something to consider in the future.
