Joakim,
Thank you for mentioning these topics. Regarding your first topic, this has been implemented and will be available in the next minor release. Clicking on the conflict link in webmail nows shows the user(s) that have scheduled/reserved the conflicting domain conference room.
Regarding the translation: translations are community driven. Please feel free to add the correct translation the appropriate language XML file. Please feel free to post the updated translations and/or contact sales@smartertools.com, and we will include those translations on the language downloads. I have mentioned in our development/support meetings that we should include any additions or changes to the language file in the release notes to make it easier for the community to provide those translations.
