Suggested channels, changing selected channel.

I have servers on my server list set to have a certain channel open, and sometimes I forget to regularly check those servers, and occasionally when I do check them, Discord will have focused me on another channel. Disable that entirely, or at-most add something like a lock to servers, so that discord wont move your focused channel.

Another thing I find troubling is the suggested channels “feature” This feature only shows ( To my knowledge) channels you have set to not show on your channel list. And Discord will as-well automatically put you in that channel. Either remove suggested channels or have an option in user settings or in-server settings to remove that feature. 
Thank you
