Why do they assume ALL Discord forums want the same thing.
Roll it back to the last version then until they can justify a change.
Its wasn't BROKE, so don't fiddle with it.
Programmers are not GOD, they serve the Discord users.
Tom... 
PS. Get this damn emoji panel rolled back.
It all boils down to difference in the amount of real estate (screen size) that is available horizontally.
And your last screenshot shows why I no longer use the side bar. I have always been in favour of the sidebar (see Is the side bar ready for prime time?) till June 2024 (see Layout changes not an improvement)
I now only use it to store references and links to useful sites and open it if needed.
Note
I don't use an iPad/iPhone.
Thanks!
I had never been aware of that either.
This 'Custom' facility is not obvious, so you need to add it as @pert described.
Using it, I can now get quickly to my usual starting place.
It's not Discord, it's Discourse. Further I agree; if it ain't broke, don't change it.
There is an old guide here: I see a side bar 👍 - #5 by sterretje
Thanks. I’ll visit that section more routinely in future.
Not directly relevant to Arduino Forum since I already found a way to add back the "My Posts" menu item, but since the discussion here also covered the development work on Discourse I'll add an update: The Discourse developers are now working to make it easier (the solution I found was fairly obscure and unintuitive) for forum administrators to configure the sidebar to include the "My Posts" menu item if they feel that having such a menu item is the right choice for their forum (as we do here):
Just when you think it's all over... and now "My Posts" is having an identity crisis. I think the Discourse gremlins have been burning the midnight oil again.
With Activity -> All selected, "My Drafts" rather than "My Posts" is marked active in the sidebar.
And with Activity -> Drafts selected, nothing is marked active in the sidebar.
And why on earth is "My Drafts" suddenly showing up in the sidebar despite me not having any outstanding drafts?
Thanks for bringing this to my attention @van_der_decken.
In response to the user feedback about the change to the sidebar menu (discourse/discourse#30277), the Discourse developers reverted discourse/discourse#30277:
The new strangeness you noticed in the sidebar menu was caused by the workaround I applied no longer being appropriate now that discourse/discourse#30277 has been reverted. I removed my workaround and so everything should now be back to how it was originally.
Thanks for looking into this. Everything appears to be back to normal... for the moment! 
OK for me too.
