1. When looking at files in ios, file viewer shows hidden files like the XML config file and .Trash. These files are not shown in OSX. Please do not show the hidden files. Since i did not know what the XML file was, I deleted it. Of course that broke my system. Hiding would be better.
2. The excel spreadsheet viewer puts the tab selector up at the top of the spreadsheet. They are partially hidden and cannot be used. Only the first tab is usable because other tabs cannot be picked.
