I'd have a few more small modification requests, which follow :
- the tooltip displayed when mouse is over a button seems to have an unnecessary empty line at the beginning : can you please remove it ?
- also, the tooltip includes a line saying whether or not variable is ignored : since it displays a preview of the command, I guess this line isn't necessary either
- while the "&" character is now properly displayed in the status bar, it appears doubled in the mouse over tooltip
- would it be possible to let the custom and settings files have the xml extension instead of dat, since they appear to be xml ? :]
