Wunderlist

Wunderlist is a very simple and convenient task manager, which will allow you to always remember all the necessary information, as well as not to forget about important data and events. There are less superfluous functions and interface elements in this application. Thus, it works very easily with it. The software can also be used by smartphone owners as a mobile operating system, so they will be able to easily synchronize tasks between the laptop and the device. In addition to automatic synchronization, you can also offer remote synchronization with the network application.

Among other things, Wunderlist allows you to assign hotkeys to various functions, as well as to set up notifications about upcoming meetings or important dates. If you want to change the importance of the task as a whole and get rid of it, I can suggest dragging it into the list to make it bigger. The last thing I would like to mention is that the application is free.
