[DISCUSS] About the need for a button to enable/disable code previewing

[Alexey Borokhvostov]

Hello!
I have created a pull request (https://github.com/apache/netbeans/pull/7694)
with the addition of code preview for “find usages”.
In the proposed implementation I have implemented a button to
enable/disable code preview and there is a question about its necessity.
I would like to hear your opinions on this issue.
