Trello is one of the most popular applications for organizing ideas, projects or almost anything you can think of. It has excellent flexibility and also a huge community that has extended the tool to a new level. For me, Trello is the place where I store all my yearly goals and distribute them on a monthly basis. Also, when I come with a new idea or an opportunity presents itself I will add it here. Similar to todoist, Trello has numerous integrations, and it is easy to find ways to combine it with other tools in your repertoire
