Trello vs Zim

There are two primary columns: the board is shown on the left and all the other controls on the right. The main means of interaction is dragging and dropping to-do cards into the various lists.

The board structure is very customizable, and includes a variety of features that help along the way: color-coding, due dates, card images, checklists with a graphics bar that allows following progress easily, and card aging for cards that haven’t been touched in a long time.

Trello has permissions at the board level as well as the ability to assign multiple people to each card. There are a lot of sharing options available and boards can be made visible for the public. It's also possible to subscribe to a card to be notified of its progress. The simplicity of the UI makes collaboration easy because it’s very simple to see the progress of each card and who is responsible for it. It also updates constantly to reflect real-time changes in progress.

Trello calls items used in the workflow “cards.” Cards are double-sided and can contain subtasks as well as notes and other details.

Card columns can be used to simulate a workflow by moving cards from left to right as they are completed, or as a way of indicating task priority.

The workflow is highly flexible as the columns are completely customizable to suit the task flow. For example, tasks can be put through a workflow "idea > approved > in-progress > pending review > released" or simply "ideas > released" depending on the granularity level needed.

This makes Trello a great solution to feature management as it's possible to set up boards to handle everything from agile sprints to a more generic to-do list, all with status management.

Trello offers a very generous free version that has no ads, no restrictions on the number of users, and very little restriction on how the program can be used. The paid features are generally cosmetic, such as the ability to change the background, add stickers or integration with other tools.

The UI is based around Kanban, so you can see all your tasks and their status clearly.

Voting, view, and calendar plug-ins further increase the functionality.

Trello supports Markdown, meaning that HTML input is represented appropriately. Cards with attachments are also rendered well. For example, images are shown correctly on the card, bug links are detected etc.

Each card can have one or even multiple task lists.

Trello works on all modern devices through the web application and has native apps for iOS, Android and Windows 8/10 devices.

Keep all of your files (images, documents, etc.) organized on their relevant cards.

The responsiveness and layers of customization make it easy for team members of various disciplines to collaborate on the same task board.

Can set different priorities to various tasks, set appropriate due dates and Story points - timing allotted to each task.

Trello offers support for features to add voting on cards, often referred to as 'power-ups'.

Works like a charm.

There is a global history system which allows to rapidly follow changes. There is also a notification system if another user updates the board while you're watching it.

Notes can contain links to other notes, allowing you to reference important information when needed. This way the user can connect and reference many different pages in the app, keeping things clean and structured, unlike Evernote, which makes this a good Evernote alternative.

If/when the app is no longer developed (or if the user simply decides to no longer use the application or view/edit it on a non-supported platform), this can still be done with any plain-text editor.

Zim will automatically create a folder structure that fits your page hierarchy and adds/removes files such as images to/from appropriate folders.

Zim supports HTML, LaTeX, Pandoc Markdown, and RST. This allows ones documents to be easily used in a wide selection of other apps.

Windows, Linux, and BSD are supported with their own clients. This is nice for those that use multiple operating systems but still want to use the same app on each.
