Hi @Jninek, @Sid,
That simplified layout is intended mobile devices, to make it easier to engage with the forums and community content on the go. This is why the Shop and Download options disappear.
The weird spacing in the bars should be fixed, however. If you try logging out and then logging in, or clearing your cache, it might flush the changes.
Are you both using desktop screens? Is it common to have your screen widths that narrow for your workflow?
If you can let me know what exactly is giving you guys trouble about the simplified layout, I can definitely look into it.
