Due to the many apps I have in my Portable Apps List, I search for a particular app by typing the first few characters. Before v10, all the apps with the same first characters appear. Further typing shortens the list until I see the app I want. In the current platform, the first character always starts with a special character. (¬),(HEX 00AC). I have to delete this character and start typing again to give the name of the app I am searching for.
For those that may not know, you can install any standalone program, (Not offered by Portable Apps.com), under the root directory within its own folder.
Normaly typing the first few characters when PA is viewable, will bring up these apps and execute them.
