Autosuggest for latex

I think RemNote is just one step away from the best latex editing tool that also supports nice self-study functions. That one step is autosuggest for latex.
I can’t resist typing proof and maths notes in RemNote, but the lack of autosuggest (compared with tools like Lyx and overleaf) just makes the process a lot slower.

Could we have autosuggest for latex, please? This would be an overkill compared to all other study tools.

This would be great! I end up consulting a katex function table more often than I care to admit.
