Translation without HTML

[wysota]

I mean a label with blue textcolor.

Don't use html tags if you don't want them to be included in the translation or set the text in code and not in Designer, you'll then have complete control over it.

Can i not define which strings wraps inside a tr()?

Not from within Designer. But you can always ignore certain strings during translation. You can even set a comment from within Designer (most or even all textual properties allow setting a comment) so that your translators know they are to ignore that particular string while translating.
