Make strings consistent "If you want to save them elsewhere" and "To save them elsewhere"
Perhaps make the end of these two strings identical/consistent which ever is prefered:
The converted pictures will be saved in the current folder by default. If you want to save them elsewhere, change the <gui>Destination folder</gui>.
The renamed pictures will be saved in the current folder by default. To save them elsewhere, change the <gui>Destination folder</gui>.
