View/Edit .RTF Files on Android

Customer uses .RTF files as storage format for Word Documents. If you try to edit them (although this is an office standard file format!!!) you can not do that with Connections (editor). You can just create a simple rtf file e.g. with "wordpad" on an Windows computer and share it to yourself with Connections. There's no edit available on smartphones (android). 

IBM Connections Editor can edit {doc, docx, ppt, pptx, xls, xlsx, and pdf annotation}, unfortunately .rtf files are not on the list. For reference:

It would be a great feature, as .rtf is a common document exchange format used on different systems.
