[Debichem-devel] Bug#214493: gperiodic: Decorate buttons?

[Theppitak Karoonboonyanan]

Package: gperiodic
Version: 2.0.10-4
Followup-For: Bug #214493
Tags: patch

How about starting with decorating the buttons with multi-line text?
In this patch, the buttons are decorated with small atomic numbers and
weights. Symbols are now bold and big, and colored according to the
state at room temperature.
