Questions about siemplify UI

Hi team,
I have some small questions about siemplify UI. Not sure if this is the right place to ask, but.
Is possible to render images that were handled in the playbook on siemplify?
I know for fact that we can download them on case wall, but I was wondering if siemplify is able to render and show to the user anywhere.
Also, is possible to format text that is shown on insight and case wall? Something like bold, italic and larger fonts..
is possible to select more than one case and make bulk actions, such as delete?

Thanks
