Hello,
Do you intend to offer a special upgrade price for universal css navigation menu extension owners ?
Would you please define your pricing policy regarding new bootstrap compatible extensions upgrades.
Do we have to consider all previous investment (non bootstrap compatible extension) as lost investment ?

Hello Herve,
There is no any upgrade price available for the universal css navigation menu owners. Currently the extension is on sale.
There are no extensions that are non bootstrap compatible. Bootstrap is a front end framework for building website layouts so you can use any of our extensions inside a bootstrap layout.
You can check our extensions roadmap, there you can learn more about the upcoming extensions: www.dmxzone.com/go/22257/dmxzone-extensions-roadmap-2014/
