Hi Jan,
Thank you.

1. Can you please post a screenshot showing the 0 issue as I am not able to reproduce it it.
2. Can you please explain which notification? I am not able to follow it.
3. Sorry about that, It may not be feasible as we have no way to know if a post was posted via Blog Categories or from backend(and since we are dealing with post, I am not in favor of it for older posts)

Please let me know and I will be looking at them quickly.

Hi Christian,
Please visit MediaPress->Settings->BuddyPress and at the bottom of the screen you will see the option to limit number of media posted in the activity. Please set it to anything you want.

Hope that helps.

Hi Hamish,
Please upgrade both the plugins.
https://buddydev.com/plugins/bp-simple-front-end-post/
https://buddydev.com/plugins/blog-categories-for-groups/

Also after upgrade, Please make sure to visit Settings->BCG Settings and configure it.

Now, coming to your issue:-
1. That is correct, I did not provide any hook to remove that. Please add following code to remove it

function bcg_remove_checkbox() {

	if ( has_action( 'bp_before_group_settings_admin', 'bcg_group_disable_form' ) ) {
		remove_action( 'bp_before_group_settings_admin', 'bcg_group_disable_form' );
	}

	if ( has_action( 'bp_before_group_settings_creation_step', 'bcg_group_disable_form' ) ) {
		add_action( 'bp_before_group_settings_creation_step', 'bcg_group_disable_form' );
	}
}
add_action( 'bp_init', 'bcg_remove_checkbox' );

3. Upgrading front end post plugin and the blog categories for groups will fix the issue.

Please update the code and plugins and let me know if that works for you or not?

Thank you
