Synonym for plug-in? [closed]

I'm making some software which allows users to enable extra features. These extra features are currently called 'plug-ins'.

I'm not a fan of 'plug-in' because of its technical connotations. I also find 'plug-in' unattractive as a word. Can anyone think of an alternative?

Solution 1:

Alternatives:

modules
expansion or "expansion pack"
extensions
add-ons

Solution 2:

Depends on what you mean by a plugin, in your context.

An optional feature is just that - a user/customer option, setting, or preference. Other kinds of plugins are sometimes referred to as add-ons.

Find out what term the people you are communicating with use for the thingie - what they are likely to expect and understand, and use that term - whether or not you are a fan of it.

Solution 3:

Why not extras or xtras?

Computing: Xtra (ISP), an Internet service provider; Xtra (Macromedia), a software plug-in;
