It seems like it is best/common practice to display page titles in templates like so (taken from black candy).
<title><% if MetaTitle %>$MetaTitle<% else %>$Title<% end_if %> » $SiteConfig.Title</title>
Assumingly the idea here is that the page Title (called Page name in the CMS) will be used unless a MetaTitle has been specifically provided to override the Title (for SEO reasons or what have you). This way there's no need to enter the title in two places unless you want finer control. It makes sense to me and I always use this convention.
Because I have the template set up as so it frustrates me that the CMS automatically fills in the MetaTitle field for new pages, which can lead to pages having completely wrong page titles down the track as unless it is cleared it will always use the override.
With the template set up as above the auto-fill function is redundant - so I was wondering if there is a way to disable this, perhaps by a setting in _config.php?
If not, could it be added to a future release? It drives me nuts! I think a config option would be okay but for me it would make even more sense to completely remove the auto-complete and change the $MetaTags function to use the logic above when rendering a title meta tag (MetaTitle if available else Title).
