**Feature Request** - *Brief title for your desired feature:* Score of usability, Rating of useful - *How would you like the feature to work?* In the component database, there must be a button for rate the component, a button for adding a review or comment. - *Why is this feature important to you?* This function is important for all of us, because we can not blindly trust the components. Why? See below. In addition, the database, especially the user-defined components, execuse me, but, gradually turns into a dump of garbage. Here's what happened: While drawing a new board based on stm32, I took from the database a suitable component for the microcontroller. This component was in the 'System Components' section (even, not in the 'User contribution'). I drew a schematic, traced and manufactured the circuit board, installed and soldered all the components, turned on the power... Overcurrent, as if a short circuit occurred. Having dealt with the reason, I found that this schematic component contained a critical error, reversal of the ADC power supply pins! Here is that component: https://easyeda.com/Mstef/component/STM32f103CBT6-chtrDd8ki With the help of a microscope and a Jedi sword, I was necessary cut the tracks and restore them in the right combination.
