1) If you change the name of a file by adding capitalization the file name doesn't change in the folders column.
index.php >> Index.php (no change)
However if you change add or remove a character or even change a letter it works.
index.php >> index2.php (change)
2) If you right click the furthest right file there is an option to close tabs to the right.. there are no tabs to the right. The option shouldn't be here.
Finally on the forum.. if you forget your password... your buggered as there is no way to retrieve it...
