This is a very minor thing, more of a rainy-day or "if you are looking at the logs page" kind of thing....
I noticed as I clicked through the devices and apps at the top of the Logs page they would jump around depending on which one was selected. Given my recent experience with HTML/CSS, I can only imagine there are some extra "containers" placed around the selected item, potentially causing an issue, but I am by no means an expert, simply a user reporting a very minor issue.
It has to do with the length of the content (logs) that are shown on the page.
If you click back and forth between two items that only have a couple entries in the logs each, you will see that the page (and menu items) don't jump around.
Now, if you click between two items; one with a few log entries, and one with a lot of log entries, you will notice the menu items jump. Additionally, you will notice the sidebar (on the right) appears and disappears.
It is the second condition that is causing the html to jump around (house of pain??).
A very minor bug. But it does go in hand with the fact I think that logs page is a nightmare. Don't get me wrong, it's super helpful... but is in dire need of an update.
