Unfortunately I don’t think Dynalist works this way. Roam Research doesn’t allow duplicate page names, but in Dynalist the document name and item name can be anything. So when there are multiple documents named “Page name”, what should [[Page name]] link to?
I think the fundamental difference is that in Roam/Wikipedia/Zim Wiki, the page name is the id of the note. In Dynalist, every item has its randomly generated unique ID. This difference is very important… Evernote/WorkFlowy/Dynalist/Simplenote etc are on the “unique id” side whereas Wikipedia/Roam are on the “unique name” side. As much as we like some of the features from Roam, such a dramatic change is impossible and also undesirable at this time, when Dynalist is already so far along.
I know some of you guys are excited about Roam, but there are also many others who are using Dynalist as usual. They are the silent ones so I don’t hear them, but they are also our users and customers and we have to take them into consideration.
Therefore, we will not make any significant changes to Dynalist that don’t align with our original vision and surprise the majority of our userbase. We’ve wanted to make backlinks more visible for some time now, so it’s nice to bump its priority given this opportunity.
Honestly, it might be better to build something new at this point, given that I’ve personally been itching to build a knowledge base app for years
