"Development Mode" is really expensive for the browser. Depending on the browser and on the system, you might encounter extreme slowness while rendering the page.
You could see an unthemed page for a while. Remember to switch it off as soon as you finished tweaking.
However, when you now turn off development mode after changing some lesss variables, you will see that the changes you have just made in the Less Variables tab are no longer active in the theme. Development mode recompiles the theme resources on the fly for every request, but in production mode the theme will be compiled once or manually from the "Resource Registries" Control Panel. When you install Plone, the included and active Barceloneta theme is served from the filesystem. These compiled theme resources on the filesystem cannot be changed from within Plone.
In the next chapter we will make a custom copy of the Barceloneta Theme which will not be stored on the filesystem, but as a copy in the site database. When you activate this editable copy, your less variables will be included in the compiled resources of that theme.
