If Zoho Docs and Zoho Writer ever merge, which one's features are most likely to continue to be fully supported.

If Zoho Docs and Zoho Writer ever merge, which one's features are most likely to continue to be fully supported.

Web based applications can disappear or get upgraded (or downgraded) virtually overnight, unlike desktop apps.  

So there is a real risk of losing functionality that you depend on.

I expect that sometime in the future, Zoho Docs and Zoho Writer will merge, or one will disappear.  Comments?

If that happens some features may disappear if your documents are written with the wrong app.  Comments?

 If I want to insure that features that I depend on dont disappear, which app is more likely to keep its features into the future.  Which app is likely to survive?  Which app should I choose (based on these criteria) ???

For example, only one of the two fully support "tooltips" in web links.  (The newer version of Google Docs no longer supports tooltips, BTW)
