When looking at my last album (see link below), there is some strange behaviors regarding the display of key words in the main menu:
1) The name of each folder name is taken into account in the key word list: these are not necessarilly key words, so why do we expect them to be present in this list?
2) The weirdest thing is that each word of a folder name is transformed as a key word too! When you press on it you often get 1 result ... which is the folder name and no image associated to this.
So why do we bother about the folder name at all? This is just misleading. I strongly recommend to remove them from the keyword list.
