I have installed the flow-netbeans-markdown.nbm version 2.1 plugin in Netbeans IDE 8.0.2.
I am running OS X Yosemite 10.10.2 on a Macbook pro.
After restarting Netbeans, Markdown does not appear in the new file wizard.
I presume it should appear in the "Other" category along with "HTML File" etc?
Markdown options do appear in the "Preferences/Miscellaneous" section.
Tom.
