You can keep all the necessary information for your day-to-day in one place with this easy-to-use application that's both super comprehensive and also very lightweight. You can even keep it running in the background while you do other tasks, and your computer won't be affected in any way.
You can set up SSuite CleverNote PIM so that it notifies you about pending tasks that you need to resolve soon or upcoming appointments and events. Organize your to-dos in order of priority with a simple but efficient color-coding system. Besides that, its interface is also pretty reminiscent of the early days of the Internet, but with the power and speed of a modern application, so it's a great way to satisfy your 2000s nostalgia.
