I am sorry if these might be hard to follow. I have been short on time but I thought you might appreciate the feedback even if it isn’t polish, vs. not getting this at all 
I want to give a shout out and kudos again to search indexing comments - real cutting edge here and helps eliminate the need for Slack, no other no-code tools do this. One big issue with comments however remains quoting and the fact that this particular way of formatting doesn’t accommodate a soft return. Soft returns (using “shift” + “return” to preserve a block of text that will all be referenced together across Fibery) are essential when typing in rich text areas if you want to effectively use references. So basically you can’t quote anything with the default “quote” format, and then get a reference in another entity that would include the entire context.
comments could be less dominant, when using them you lose visibility of a lot of the rest of the entity - would help if you could just quote comments ala discourse, and maybe have less intrusive comment boxes across the interface, so you could comment quickly while still seeing most of the rest of an entity.
Search issue I posted about where you can’t filter w/out typing something: Filters for recent items in search
often entity names cut off, can’t mouse over relations (in collection area) and see title, although you can see that in bottom menubar of your browser as a workaround
Inline entity creation with a .com in the name issue that I have the bug logged about, I never got a response - Typing a ".com" with hashtag inline breaks flow of text - #6 by B_Sp
Newly created entities can take 15 - 20 seconds to appear in connection areas. This can be frustrating in meetings when creating a new entity, then trying to link it somewhere…it won’t show up in the results for this amount of time.
When trying to create bulk entities in rich text, you have to use bullet points and can’t use soft return, so references are lost. It’s easy to make a list of items you’d like to convert to entities with a soft return, but Fibery won’t allow bulk creation if you don’t have a bullet list format.
Also using keyboard to create bullets is difficult, not intuitive
In some cases I don’t understand, in many-to-many collections the default does not show a list of related entities to choose from. Recently in one case I was presented with just a “recent” item that I could not remove from the selector without typing in the relation field (I have to type and replace the default text “Create a new document…” when in other cases I get a selection of choices - and I don’t understand the order of those, either). In this case I am not even sure when I accessed the item showing as “recent”
When using big button to create an entity with a start date, you can’t continue to hit “tab” on a Mac to move the focus to “create,” so you lose the speed of keyboard shortcut. You can do this with the “tab” and focus when inline in entities with # (except if you have a .com in the title of the entity per the bug I quoted above)
Again I hope all of this is helpful, thanks!
