Hi Philip,
Thank you for taking the time to share your thoughts, and thank you for your support of Bear.
Regarding the above, we do have a Table of Contents feature available to test within the latest version of Panda. Post about it here: Panda release notes 1.0(2208)
To access the panel, you can use the ⌘⇧Y shortcut, then switch to the second tab.
Regarding backlinks, yes they are something we’re thinking of adding as an option into the info panel.
However, we’re waiting to do this until after it’s migrated from Panda. This is as note links and backlinks only work for Bear.
Regarding the overall search experience in Bear, this is something we’d like to keep improving on, particular in-note searching for iOS.
This (in-note searching for iOS) has become a popular request, and rightly so. We can completely understand why. Therefore, it is now something we’re currently working on.
Thank you for the above suggestion, I’ll pass it onto the rest of the team to Bear in mind
