Hi,
Firstly, I really like Dropbox and I use it a lot. However, it is lacking a feature which would prevent problems.
Both the Android and Windows lack a refresh button when viewing a folder.
For example, if I rename a folder and add some new files to the folder. I tell my wife that her scanned document, which she is desperate to email to somebody, is in the new folder but when she visits the folder it just shows the old folder name and the new file is missing. She knows its in there but it does not show; because there is no "Refresh Folder" button there seems now way to fix the problem.
Any suggestions for an interim solution?
