Good effort, but i dont feel like it addresses the larger issue. The biggest problem i see in the admin sidebar is the inability for plugin developers to place their menu items in the correct location.

Most developers place them as main menu items without rhyme or reason. There is no point in having the Facebook Pixel plugin visible at all times since it is a “fire-and-forget” thing that usually only needs a one time setup.

Move tools to the tool section, move settings to the settings section etc. anything else just clutters up the interface needlessly.

That combined withe the fact that more and more plugins use ugly colored icons that makes the admin area look like someone dropped a bag og skittles.
