OPML Viewer Parameters

I designed the OPML Viewer to be easily integrated into other websites.

These are the parameters that you can pass to customize it:

Parameter	Description
`url`	The URL of the OPML file to display.
`return`	The URL that links back to your website. Optional: it will default to the root of the `url` parameter.
`sort`	How the entries in the tree should be sorted. One of: `name` - by name (default) `url` - by URL `dirfirst` - by name, but directories first `original` - in the order they appear in the OPML file
`transform`	How page names should be transformed for display in the tree. One of: `initialcap` - Uppercase the first letter, leave everything else unchanged (default) `original` - Keep exactly what is in the OPML file `titlecase` - Uppercase the first letter of each word, lowercase the rest of each word
`showmode`	Set to `1`to show the light/dark mode switcher
`showlanguage`	Set to `1`to show the language switcher
`showexit`	Set to `1`to show exit toolbar button (goes to the URL specified by `return`). The main icon also goes there, so this is optional.
`showdebug`	Set to `1` to show a toolbar button to view the logs. You do not want to have this on in production, but it can be useful when troubleshooting
