The Applied Steps pane on the right (in Power Query) auto generates step names using normal spaced words. This is great when reading the step names in this pane. There is, however, an unfortunate consequence of this naming style. The M Code is more difficult to read and write (although reading is the main issue I see).
Here is an image showing the difference in readability between the 2 approaches.
I am the opposite. I use #"" for all variable names, even those that do not contain spaces or special characters. I find this to be easier than needing to remember the 2 possible syntaxes. Also, the #"" adds some visual bulk that makes the variable names stand out a bit better. Whenever I see #"", I know that I'm looking at the name of a query, variable, column, or field. Lastly, #"" lets me write the variable name however I want without restrictions like needing to not use spaces or special characters. You are no longer forced to write like a programmer. You can write largely like you normally would and your code will still be valid, and I think that this is great.
In the image that you shared, the camel-case step names in the pane are harder to read than the default names. The solution is not camel case. The solution is to have a way to get the effect of #"" while still being easy to type and easy to read. Maybe something like surrounding the variable name in single quotes is the solution (e.g. 'Variable Name').
