Can you recommend a free minimalist documents app? (replace Google Docs- can be offline)

Hey Lemmy! I'm ashamed to admit I haven't yet quit Google Docs. I think I should especially since I got a lot of documents which I really have no reason to keep online, I've been doing so out of lazyness as I'm used to GDocs and its ease of use.

I'm looking for a text editor that lets me paste images straight from my clipboard into the documents, this is a must for my workflow.

Another feature I use a lot is the side menu/index, which is created automatically when I insert a header and lets me jump quickly to any part of my document.

With that in mind, the search function is also essential, I need this to either have a search bar or work with ctl+F

Of course I need some basic color and font size variation, and having the ability to create tables is handy but I don't need any kind of math functionality.

I could use Libre Office but I'm looking for something bare bones and lightweight. I haven't used LO in years so it may have changed, however from memory it's pretty well fleshed out and I find all the extra features distracting especially since I don't need them. I'm not sure though, perhaps I'm wrong and you can convince me?

Have you got any suggestions? TIA
