Automatic width of taskbar buttons to show full text of labels

It would be very nice that tweaker will adjust width of every taskbar button to show full label. So buttons with short labels will not occupy a large space of taskbar allowing buttons with long labels show more useful information. For example, we have 2 opened documents:
Bonus Appendix 1.pdf
Bonus Chapter 1 (changed).pdf
and we will see all label and will not muddle them.
