It functions on the bleeding-edge. And for it to work I can only imagine the effort put in to stay ahead of the curve. An exponential curve too.
Not really a 'dislike' but the cost. You get what you pay for and I'd worry if the fee went down, honestly.
I've lost count of the amount of NDAs I've signed so specifics are difficult. What I can say is three of Forbe's top 100 companies keep paying me!
Easy usability for a non-developer and a vibrant community.
Pricing can be made a little flexible to suit all types of customers.
I am using oxygen as a writer to create portfolios. I do not depend on a third-party developer to create such sites.
The multiple build format provided by Oxygen is impressive. The multiple transformation scenarios. Very description alerts, errors and warnings. XSLT debugger and associated stylesheet. The integration between the parallel projects is amazing. The option to validate multiple projects in one go. Cost effective.
The editor window can be smoother. The windows have nested panes and too many drop options on the tabs listed. The long list overflows onto the editor. Increase the number of tabs and optimum options for practical usage of the tool. They grey and black UI. The congested options present on the DITA Maps manager. Online Help content is unavailable. Cloud storage can be available.
We had a problem with multiple documents on multiple platforms. Oxygen solved the problem by providing a one dashboard solution. Structured Authoring. We used DitaExchange earlier which was very slow. Oxygen is DITA based and quick. It supports varied output formats for the same project. It also solved the problem of cost.
