Finding appropriate tools for boosting productivity can be a big challenge.
Be it a tool to remember the passwords or to make notes, a good engineer has always made the best use of different tools.
A good engineer not just understands the importance of tools but also knows the limitation of each tool.
Just like there are no best practices, there are no best tools.
There are tools suited for each activity and the same tool might not be the appropriate one in another instance.
It is therefore very important that an engineer knows at least 2-3 tools from each category.
@ajay184f and I have made the work of tool hunting easy for you. You can find tools arranged in various categories, and use cases.
