GVG this response is uncalled for. When you join a community newly, learn to behave in like manner. People put in a lot of effort into developing these extensions; the least you can do is attack them. Luceos had already responded in another discussion that in future they'll look at putting screenshot.
Read the first post of the extension, install them if the description fits your purpose, and test the extension. If it meets your purpose you keep them otherwise you uninstall them.
Alternatively, you can create your own extension. No one is stopping you.
