Geektools clock not updating
Every skin's code is completely open, and can be tweaked, modified or even completely rewritten using any text editing software.
If you only want to download skins from the Internet and use them as-is, then the answer is "none." Rainmeter provides a basic user interface for managing your library of skins, saving and restoring layouts, and changing basic settings such as a skin's location, transparency, and "always on top" behavior.
Every skin works differently, depending on the choices of that skin's individual author.
However, all skins are made from the same building blocks: measures, which gather information from your computer, a website, a text file, or some other source; and meters, which create visual elements in the skin's window, such as frames, borders, backgrounds, images, text, charts, or buttons.
I had a problem when I was asking it to run "top" where it slowed geektool down a bunch.
I didn't realize that it was running the task over and over and I had to remove it. It didn't slow down my computer, but it was a pain to change anything in geektool until I fixed that. When you keep refreshing a big script, of course it slows down your Mac.
All of these things are made possible by Rainmeter's unique code language, which allows a skin to access functions and resources built into the Rainmeter application.
It includes a powerful and flexible set of features, and we are continually surprised by the creative ways that those features are used.
However, it is important to understand what Rainmeter does In short, you cannot usually download and apply someone else's amazing desktop transformation in one click.
Rainmeter is a free, open-source application for Windows PCs.
It is a platform that enables skins to run on the desktop. Some skins are very simple, single-purpose tools, like Windows desktop gadgets, or "widgets" on an Android device.
