The filter system is there to sort out ideas not only based on subject matter, but also on the intended group. Here's an example: You can apply the following filter and will be shown only the ideas that work just for that:

Before an activity is set to go, leaders usually plot out a general scheme. Many use an excel worksheet or a basic word processor to do so. Timetables are specifically meant for planning and preparing activities. You can create an exact time-line, arrange and re-arrange ideas using 'drag and drop', assign tasks, display material lists and much more.

Pinboards can help you to organise your collections and compilations of ideas. You can create as many pinboards as you need and can even edit them together with your team. You can also choose whether your pinboards should be shared publicly or kept private, so that only you can see them.

You can create a group and mark which ideas you have already tried out with them. Then, using filters, you can search for ideas that you have not yet tried with a specific group. This helps you to quickly find new ideas, as the ones you have already used are no longer shown.
