it does not appear the topic cover settings
Hello, @Javier_Badani. Can you please specify the issue (and maybe add a screenshot, if possible) so that we could look into this?
Thank you for the screenshot, the above-mentioned tool was updated a while ago and the icon was removed from the toolbar.
Now all the topic covers are customisable and you can adjust your topic cover by simply clicking (and right-clicking) on them.
