You can see that:

1)
In the "dnf history" command, there is a lot of "install ..." in the second column. Which I wouldn't really like to see, because there is a separate column no. 4. for that information.

2)
Also column no. 4. seems IMHO unnecesarily wide

3)
Asi that you can see also comments in the second column. They were created with command:
# dnf --comment="Some comment" install some-package

However they are stored with the "--comment=" part, but without the quotation marks. Instead of the "--comment=" part, I like to see that actual comment.

4)
What would be most awesome, to see the whole, not clipped, comment.
Even if that would mean to use aditional option. Like f.e.:
# dnf history --wide

5)
The "dnf history info <number>" doesn't show the comment, aside from the actual command line input - which is again without quotation marks used around that comment.

-----

I'd like to use comments to add some aditional information to the transaction to my later myself.
Because - you know - who remember, why he installed that weird package 11 months back?

Comments should make orientation in the DNF history easier.
It should IMHO help the system administrator understand, what he was doing. Help to hunt down his mistakes. Or help him to reproduce something he managed well - but he forgot which packages he needed for that.
It should be explanatory for other sysadmins to understand how the server was set up.

When I remember - "IRC server, what did I needed for that?" - I should easily find a pair - comment and list of packages changed on the system.

Comment option was added here:

History output width was fixed here:
