When I share a URL / Webpage it should be useful to automatically add a specific tag (#ReadLater) to it, so I can easily filter the inbox
There is an alternative browser button https://chrome.google.com/webstore/detail/dynalist-bookmarker/mbempfckkkcncamnaopmfagmocdmlknf
It lets you choose a default location that is not inbox, if you want to make a #ReadLater node, and everything automatically clips there.
Thanks, how do I install this on my iPhone?
You would need a different app for phone, unfortunately.
Search the app store for dynalist
I know on Android there are apps that let you set several different inboxes. Not via the share dialog, but via a widget.
