When changing a filename manually, or when changing a folder name in the favourites sidebar, I have noticed that PM will not allow me to make only an uppercase or lowercase change. In other words, a photo named "bob smith" cannot be changed to "Bob Smith". The only way to do it is in 2 steps; first change something else as well as the case, like "Bob Smith 1", then go back in again and remove the "1".
Not sure if this is normal, and if it was done on purpose for some reason. It certainly isn't a life-changing issue as it isn't that common that I'm changing names manually, but I found myself having to do the 2-step name change a fair bit on a particular project recently and it became a bit of a pain, so thought I'd mention it to see if it could be changed. Thanks.
