Test: Open the "idosg | DS Web IDE" project in the edit.html page on beta3.

1) Run this on the console to time the merged plugin code:

localStorage.clear(); localStorage.onePlugin = true; localStorage.consoleMetrics = true; location.reload()

2) Run this on the console to time the unmerged plugin code:

localStorage.clear(); localStorage.consoleMetrics = true; location.reload()

beta3 that beta3 had non-minified code when the times were taken.

Times for just a refresh (location.reload())

Which makes sense because only the necessary plugins are loaded if the metadata of the plugin is cached in local storage.  In this case, 1) loaded three plugins and 2) loaded five plugins.

The code released merged 13 plugins into one.

In comment #1, 1) loaded 11 plugins and 2) loaded 22 plugins.

The code has been enable by default.  There is still room for improvement here (i.e merge other plugins: javascript, git, etc). But I think we should open separate bugs as necessary.

Some of the plugins cannot be merged since they have UI compoenents (i.e JSON editor and Image Viewer).

Plugins that are loading the bootstrap cannot currently be merged either.
