Can you share a screenshot or something? Are you using a custom CSS or a full-screen mode or something? By default, the title should always be visible at the top.
Do you have any examples of other note-taking software where this acts like you describe? (rather than spreadsheets.)
Otherwise, if you are talking about freezing the first line in the content body of your note, that seems pretty specific. There is nothing in Obsidian which implies or forces your first line to be an H1 header for example. (Also please be careful when using the word “title” because in Obsidian “title” means the filename of the Markdown file.)
- What’s to say the the first line of your content is the “title”?
- Should it ignore YAML front matter or comments or tags at the top?
- Do you imagine this as a Vault setting? Or should it store this information per note? Like in a spreadsheet, you have to choose which columns/rows to freeze.
I wonder if this is something that is currently possible with CSS. You could define a certain custom H1 class. Maybe it can have CSS properties that forces it to render at specific vertical location in your note. (On the other hand, if you defined two of these headers, would they overlap each other? Or stack nicely?)
