Currently all labels are converted to lower-case after entering. This is a problem with some languages other than english.

In the german language for example, all substantives start with a capital character. Substantives are very often used as labels. So whenever someone uses german substantives as labels, the resulting list of labels looks just wrong. At least one customer considers this as a bug instead of just an improvement.

Since Java provides case-agnostic string search functions, it is technically not a big problem to fix.
