To download user must 1. Share 2. Select Newpipe 3. Select download
Adding one more line to menu to download should not be an issue

Duplicate of #2171.
Sorry for that.
I did search but didn't notice this issue
In regards to templates,
Does not appear in app.
It should appear automatically when opening a new issue
You should open a bug for your app also.
Also for a simple adding new option, it should have been looked at sooner,

as you can see many duplicates of this issue were closed, so yes, this is a highly requested feature ;-)
I would be ok merging this before the bigger work is ready, mostly because I am not sure if the bigger work will ever be suitable for everyone, and it will surely take some long time. So in my opinion you can go for it, thank you :-D
The implementation should be rather simple, you can take a look at the code for the "Download" action in the open/share menu.
Not to criticize, just mentioning it because it is a simple addition that has been requested many times, and there is no obections to adding it.
As you can see, a user was interested in working on the feature and was given the go ahead. We can only wait now.
