UPDATE: Nevermind. I'm new to the app. You have this feature. I just had to right click the highlighted text. I'm on PC.
Adding the ability to add a hyper link to an entry would solve this (and solve linking to other things as well). Unless you can already do it and I just missed it.
It would STILL be great to integrate Google photos, based on timestamp, though.
E.g., my entry today: ..."Christmas PJs picture (full URL) we tried to take"
I'd prefer to just be able to hyperlink "Christmas PJs picture" to the URL of the Google photo I want to link to.
IN ADDITION to this, it would be great to integrate Google photos taken the same day as an entry. But in the meantime, just adding hyperlinking would provide a generally very usable solve.
