Thanks for your comments. What you are describing applies to any language, including English :-)

The settings in most of the dialogs are descriptions of features that would make little sense to a user that has no experience with IRC because many of them refer to behaviours that can only be understood after using mIRC/IRC for some time.

There are no plans to add information icons to all of the dialogs to explain their features. That is the purpose of the help file and the help button in the Options dialog.
