See title.

Thunar 4.17.8

assigned to @SKefalidis

added 5. Toolbar label

added 5. Plugin - Custom Actions (UCA) label

mentioned in merge request !214 (merged)

For the sake of completeness, here as well the 'why':

Some people might have 10+ diferent folder UCA's, which than would make the toolbar look a bit funny.

(Did not think about it at the beginning)

mentioned in commit d2887d91

Fixed by above commit, to be released in thunar 4.17.9
