Cherry tree is an application which will be your best helper for that. A small program in which you can include any data, information, note … and, what is really interesting, in which you can organize it perfectly, in a structured and hierarchical way, in order to be able to consult it with a great agility.
The application has a very clean interface, in which you have the central area to write or write whatever you want and a menu on the left side. It is in this menu that you will place all your small note files, so that at a glance you can click, for example, on the title “buy” and you will open the various notes that you have. The hierarchical structure that allows us to create is really handy for locating any point.
