Is "and then some" an offensive expression?

I started an internal email discussion with the title "Editorial: link issues, some spelling issues and then some".

However, upon rereading my own mail, it occurred to me that this might express something like "I found some link and spelling issues, but really, much more is wrong here", implying finger-pointing to the receiver for how bad it is.

Yet, I wanted to express something like "I found some link and spelling issues and some uncategorized minor stuff".

Is the implied meaning of the original sentence relatively rude to English natives, or would you consider it more or less neutral? How should I rephrase, if at all?

And then some, according to The Free Dictionary, means:

with considerably more in addition: This project will take all our skill and then some.

Note that in the above definition, the considerably can be ignored; I haven't seen the phrase used to mean anything more than with more in addition.

It's not a rude expression at all, except (since it's an emphasizing phrase) when you apply it to other people's mistakes. In essence, you're saying they made a lot of mistakes, which isn't polite to emphasize.

I'd call offensive too strong a word for it, but it isn't particularly friendly. At best, it sounds rather arm's-length.

I would suggest you use "Editorial: link issues, some spelling issues and some other details" so you don't sound judgmental.
