Here is the summary of the changes/fixes that are ready to go - just in case any of them are impacting you:

### New features

- A new `--syntax-highlight-height` CSS variable has been added to allow the maximum height of syntax-highlighted blocks to be set. If the content exceeds this height, it becomes scrollable. This is useful for preventing very large blocks of content from taking up too much space on the page. The default value is `22em`, but you can set it to whatever you like in your CSS. You can check out its use on the Variables page in the Markweb demo where the height is reduced to `9em`.

- For Markweb, there is a new `uibuilder.markwebEvent` variable. Currently, this is only set/updated on page-navigation. It shows the old and new URL's. The Variables page in the Markweb demo has been updated to show how to use this.

### Bug fixes & tweaks

- When the runtime plugin is loaded by Node-RED, the `uibRoot` folder should be in 1 of 3 possible places. An overridden location (`uibuilder.uibRoot` in `settings.js` if provided), `<userDir>/<uib.moduleName>` (e.g. commonly `~/.node-red/uibuilder`), or `<userDir>/projects/<currProject>/<uib.moduleName>` if Node-RED projects are being used. The last of these was not working correctly. This is now fixed. In addition, the logic for determining the `uibRoot` location has been tidied up and made more robust. [Reference](https://discourse.nodered.org/t/uibuilder-new-release-v7-7-1-new-features-and-bug-fixes-extra-bugfix/101164/7).

- Markweb:

- For some users, the Markweb was reporting 0 files to be indexed. This appears to be due to the `ignore` parameter passed to `fgSync` (which uses fast-glob). [Ref](https://discourse.nodered.org/t/uibuilder-markweb-too-dark/101168/13).
