I believe we should be renaming:
'Show button bar 2 (vertical)'
to plane:
'Show vertical button bar'
The filename is clearly named 'vertical.bar' plus a reference to #2 is a bit redundant since we also have subbars for the main button bar. Someone could misconceive a subbar as bar 2. Well, presumably we didn't have the parenthesis explanation in the first place but still we make things unnecessarily complicated with numbers.
