I had difficulties to re-order the function list in sidebar. E.g. I'd like to put *add items* at the top, as most users use this the most frequently.
Today I happened to make a change on the po file and found a work around.
Open the core po file, add "<<" & ">>" before and after the function name, e.g. add items, delete items, then they'll be put at top.
So you can also group the functions to the album. you can add "Album: " before the function names. So they'll be shown together.
Merry Xmas.
