It would be very helpful if we could define our own garbage types (with translation)

Once a notification has been delivered to the user's Alexa device, there should be an option to revoke it.

When I say "alexa turn up the volume" I want it to ALWAYS turn up the TV volume. Instead, sometimes it turns up the TV volume and sometimes it turns up the volume on my echo, seemingly randomly. Let me set the preference for phrases manually.

My father is approaching 80 and lives far from me. We have set up some smart devices to help him be more comfortable, such as routines. Unfortunately, he isn't very tech savvy so it it tough to change routines or help when he runs into a problem. It would be very helpful if he could give me permission and I could access his smart home network to fix things remotely (like changing routines). I wouldn't need access to his Amazon account, but rather would want to access his "Amazon Alexa" app for his home.

“Alexa Pause reminders until tomorrow”
If you have a reminder to take pills that keeps reminding you until you take them, then you can say Alexa Pause the reminder until tomorrow. That would be very helpful.

Be able to control the colour of rgb lighting dependent on thermostat temperature or room temperature

Each login that belongs to a Household Account should be able to only have communications, such as alerts of delivery come to the device registered to a particular login.

It would be useful to have a skill in which to define voice activation commands and the relative URLs to call.
For example, if I say "Alexa, do this thing" a custom HTTP call is made (eg http://192.168.1.46/roller/0?go=Stop)
This way there is the possibility of piloting any device that supports HTTP calls.

I wonder if it would be possible to program a routine that would announce calendar events like birthdays or anniversaries as part of a wake-up program and ask the "recipient" if they want to call the person later that day. And if the "recipient" says yes, then Alexa will both say, "OK I will remind you to call [birthday person] later today" and then make the reminder. But if the person says no or remains silent the routine can progress normally.

Make it possible to program "volume controls" into a routine; for example ramp up the music in a wake up routine. I'm using a routine to help my aged mother-in-law get going in the morning while I am at the gym, so that I don't have to start from scratch when I get home. But her complaint is that it is too abrupt. It could also be useful ramping down at the end of the evening.

skills like TuneIn or Spotify, when I command Alexa "what song is playing?", returns me "You're listening to [name] from [author, podcast]. How do I implement this in my radio skill?

When you set an alarm and set it to play the radio, it would be good if you could get that alarm to turn on a device such as a light at the same time.

I currently have an alarm set, but then have to have a route created for the same time as the alarm to turn on the bedroom light. It would be great if this can be done in an alarm

Currently you can have one customised action at the end of a routine. It would be great if we could have more than one and have them anywhere in the routine.

Having a single routine for example turn light on, but then have the ability in that routine to set multiple on and off times.

So instead of having 3 or for routines to turn a light on, you have 1 routine with multiple times

This is more Alexa core capability, but I would like to see the ability to assign specific skills or routines to specific Alexa devices. For example, if I put an Alexa in my garage, limit the capabilities to playing music and outside lights, so if someone is outside my garage and they yell a command to disable my alarm, it wouldn’t respond.

assign swear jars to family members and ask Alexa to add coins/dollars

Need to provide an alternative to invoke a skill with multiple names instead of single name.
