Simple to use, works a treat

Tested on 4.1 multisite. Exactly what we needed and lightweight thanks!
A couple of suggestions:

1. I’d put your ‘All comments’ menu item as a sub menu under “Settings”. Not really necessary to have its own menu item as once its setup you don’t need it again and it takes up a log of valuable menu space

2. To make it as flexible as possible might be worth thinking of adding some optional params to the shortcode so you can have different pages showing different types of comments

e.g. [bt_comments type=”posts”] [bt_comments type=”pages”]
If left blank i.e. [bt_comments] it would simply show the default settings.

Currently you can only show what is setup in the options page for ALL shortcode instances.

3. For ease of use, have both the pages and posts setting TICKED by default. Most users (feedback from others as well) do the following:

a) Activate the plugin
b) Add the shortcode to a page
c) Wonder why nothing is being shown

You shouldn’t really need to ENABLE the posts and pages (tick the box in the options) as WELL as activating the plugin. Out the box it should probably have these ticked, then let the user untick if they need.

Great work, thanks again,
