Problem of Not Being Able to View Entire Long Notebook Titles

1.) For desktop, copy and paste the below code snippet into your userchrome.css. Adapted from the Remoods theme notebook item scrollbar code, it provides the solution you propose.

.sidebar .list-item-container > .list-item {
  display: flex;
  border-bottom: 1px solid #FFFFFF;
  overflow-x: scroll;
}

I don't know any solutions for mobile.

2.) Prefixing search with a slash / will switch to basic search. This can be slower than full text search, but doesn't ignore non-alphabetical characters. For example: /"- [ ]" returns all notes with unchecked checkboxes. You can verify this information and more from the Searching docs page.

3.) I don't know any solutions for this.
