Capitally keeps track of all the changes you make in your portfolio. This feature allows you to modify your portfolio without fear of breaking things, as you always can undo any change. It also lets you review any past actions.
You can access the History, Undo and Redo from the menu in the top right corner.
Removing History
If for any reason you wish to erase your full history and only keep the current state, you can:
Export the project to JSON
Create a new project
Import your data back
Delete the old project
Modifying the State
If you want to modify multiple items, and you prefer to do it in a text editor for any reason, you can:
Export the project to JSON
Edit the file in a text editor that supports JSON, while keeping it's structure
Import your data back
If you're not satisfied with the result after importing, you can always undo the import and try again.
When import from a JSON, objects with new ids will be added to the project, while objects with existing ids will be merged with the existing ones. It's currently not possible to delete objects through imports.
