Dunno because it can be a bug or it can be an useless feature.
While working on the editor (1.3.x) I added a small hack to have buttons on multiple lines.
I see that now the editor keeps the buttons in one line, but the php code still has the "new line" mark.
Do you prefer the single line or the double one?
Note to self: if we want to keep the multiple lines I think it's better to change the symbol that defined the end of the line (currently a double pipe || with I'd say an exclamation mark !).
Exclamation mark is used in PHP for =/= so would be better to use something else.
My 2c: one line is good if you have the width, but the buttons should stack well on narrower screens. This should work with just css. No php should be necessary.
That's how already works: one line that automatically splits on multiples if it doesn't fit into the screen (forgot to say).
Though there are advantages with predefined multiple lines, for example you don't have to go and search for a button every time (or at least most of the times) you resize your window.
Yeah but you can do that by grouping them, so they line break in chunks instead of individually. Still don't need php.
Also, the css should be tweaked so there is a space between lines. About 6px or so at a guess.
/me is css dumb, you know.
