I see couple of issues with Page heading.
1. It doesn't obey the page display settings of Menu item. It always displays the Menu title even though I have selected show heading which is different from Menu title.
2. There is a RSS icon showing up for H1 title which is different from the RSS icon that shows up when RSS option is selected in eDocMan configuration.
Looking at the source code, I see the following line is causing the issue:
file: ../categories/tmpl/default.php
line 40: <h1 class="edocman-page-heading"><?php echo $this->category->title;?><i class="icon-rss"></i></h1>
I have fixed issue 2 with an override file where I have removed the <i> tag. But wonder if there is a purpose to this markup.
To be honest, right now, EDocman doesn't handle the page heading / page title from menu item very well at the moment. So the way you solved it is correctly and you can stay with it. I will address this issue in the next release of EDocman
