What I’m trying to do
I am glad to see the new bookmark plugin. I would like to use it to mark special blocks of text.
Things I have tried
In order to do so I have created a hotkey for this action. Using it the bookmark editing dialog pops up.
Unfortunately I cannot give it my own title. I must use the one which is proposed in order to be able to find the bookmark later on. Otherwise nothing is found. But this does not really help having more than one bookmark in a document with lots of blocks.
From time to time you will have to update the Installer version, yours is far off from the Current Version. You update the Installer version by downloading the Installer again from https://obsidian.md/
The release notes even state this sometimes, as it is needed to update the Electron version.
