hum, I'm glad your team realizes this is a important feature. In considering a usable Word alternative, our company has been looking at all options. At this point your competitors are more advance with their editors even thought they released them later.
Any company wanting to provide this word (docx) import/load feature in the editor for their customers is going to need this along with other things otherwise the formatting gets screwed up and things get stripped out. Our customers would cause major support nightmares not to mention the bad PR if they used this and their documents keep getting majorly tweaked. I would go as far as to say any serious company using this component would have the same issue. FYI - if you promote your ability to import Word docx files. Then you better allow 1 to 1 import, or else this is really a bad marketing play.
i.e "we support docx (word) import, but first you must take out all your columns, all your charts and all your shapes etc." just don't see customers buying that from us.
looking at the competitive solutions, one in particular does a kick ass job however they lack in the "tracking changes" which your team did a kick ass job.
not sure whats more important now...screw up someones document when importing and give them tracking...
hope this feature gets moved up to top priority in the Editors.
