I use the commercial version of this app -- BlogTouch Pro -- on my iMac. It is a feature-rich app for working with blogger.com, and well worth the $5 pro price, in my view.
However, one thing I find annoying is the fact that there is no way to be immediately returned to the same folder from which I am currently uploading images to my blogger account.
In other words, I normally upload ten or more images in sequence which all pertain to the same general theme or topic. The problem is that each time I click on the "Choose Image" button to add the next image in the sequence, BlogTouch Pro takes me to my "Documents" folder, instead of back to the same folder I was in previously. As a result, I have to take the time to navigate to that same folder for each image that I upload. As I said, this is very annoying, and wastes a small bit of time.
To make matters worse, there is no way to set this, because the "Preferences" option under the "BlogTouch" menu is grayed out.
In short, it would be great if BlogTouch Pro would give me the option to go back to the same folder, instead of always taking me to the "Documents" folder by default.
