What feature would you like to request?

At this moment, the plugin has important functionality covered with unit tests, but there are no end-to-end tests yet to provide closer to real-life user experience. There are many repositories on GitHub doing e2e for Obsidian plugins, so I tried to follow this path as well.

Currently, the test/basic-e2e branch contains the initial (super basic) configuration for Electron in WebdriverIO that creates a test vault environment inside Obsidian for testing (check helpers.js)

The problem is that after launching tests, the initialization fails with the following error:

 Error: Can't call click on element with selector "div.modal.mod-trust-folder > div.modal-button-container > button:nth-child(1)" because element wasn't found
at async Object.initializeTestVault (/test/e2e/helpers.js:26:3)
at async Context.<anonymous> (/test/e2e/e2e.spec.js:4:2)

The selector is correct, so it's kinda tricky for me to understand what I'm doing wrong with the webdriver.

The perfect goals at this stage would be:

1. Fix the initialization of the test vault configuration.
2. Go to the plugin's settings and check that the default configuration is set.
