Sharing one idea I found useful for paper writing:

Do NOT ask people to solve correspondence problems.

Some Dos and Don'ts examples below:

*Figures*: Don't ask people to match (a), (b), (c) ... with the descriptions in the figure caption.

*Figure caption*

Use "self-contained" caption. It's annoying to dig into the texts and match them to the figures. Ain't nobody got time for that! ⌚️

Also, add a figure "caption title" (in bold fonts). It allows readers to navigate through figures quickly.

*Notations*

Give specific, meaningful names to your math notations. For example, the readers won't need to go back and forth to figure what each term means.

*Which*

I found that many of my students love to use "which" in their sentences. I hate it ... because I often cannot figure out what exactly "which" refers to. Break it down into simple sentences and spell out what that subject of the sentence is.

*Respectively*

It's hard to parse which corresponds to which in the sentence that ends with "respectively" (have to solve a long-range correspondence problem). Break them them so that one sentence talks about one thing.
