AutoSave allows you to save documents for a period of time
Warning if you accidentally close the card
One problem that users are concerned about using Word is that it does not warn you if you close the working tab that you are working on if you have not already done the changes. This will cause you to regularly conduct the process of working with the document on this application if you do not want to be startled when you remember the process has not been saved.
Support other document formats
Docx, xlsx, pptx are good but not popular with Office 2003 format
If you want to use Microsoft Web Apps, you can only save and download MS Office 2007 format documents including docx, xlsx and pptx. This will be a big problem for those who only want to use the MS Office 2003 doc, xls, ppt format. It will also be more convenient if you can work with other popular formats such as RTF, csv html and pdf which are supported by Google Docs and Zoho.
Obviously, Microsoft wants to encourage people to update their new Office software and switch to newer file formats, but this kind of encouragement makes users more uncomfortable.
Expand the ability to fully support features for web browsers
One of the interesting features of Office Web Apps is that it allows users to simply click on a button to open a document directly in the desktop. If you're editing data in Excel, just click the ' Open in Excel ' button, your data will open as if you were working with a desktop application, but you still have to save it online. The problem is that this feature only works with Firefox and IE browsers on Windows, does not work with all web browsers on a Mac.
The main reason is that the functions in Excel, Word, OneNote and PowerPoint are based on Microsoft's ActiveX platform, which is not available on Mac or other browsers in Windows such as Chrome, Opera, and Safari. It would be better if Microsoft could extend this functionality to all browsers and Mac computers with MS Office installed.
No longer friendly with Mac OS
Mac users will see an annoying feature in Word, this happens as a way of binding to the function shortcuts. For example, with MS Office for Mac, users can use the command combination by typing ' command ' with a letter key, such as ' command + b ' to bold, ' command + x ' to use the cut command , ' command + c ' or ' command + v ' to paste.
But in the Word Web App, users must use the ' control ' key instead of the ' command '. This is probably because Microsoft wants to use the CTRL command to combine key words instead of discrete usage as before.
This may result in Microsoft failing to conquer the Office Web application on Mac OS, giving rights to Google, which focuses on computer users' habits.
In general, in general, Microsoft Office Web Apps is quite good, if improving the above 5 things, this would be a better product, can compete strongly with online services from Google and Zoho.
