[IDEA] for 3 extra features for $:/plugins/tiddlywiki/savetrail

[edgarasben]

Is your feature request related to a problem? Please describe.
I would like to export static .html or .md files for my static website. Currently it's a bit of a long process using JSZip library plugin, to export my tiddlers and copy paste to my website directory.

Describe the solution you'd like
There is an existing new plugin called $:/plugins/tiddlywiki/savetrail which automatically exports tiddlers to Downloads folder as JSON files. I would like 3 updates to this plugin:

I wish the plugin would:

1. Let me export not only JSON but also .html files, and ideally also .md
2. Let me define a filter, so I can use tags and export only those tagged tiddlers, instead of currently, all modified tiddlers.
3. Let me define a folder besides "tiddlers" folder on my TW Node.js project where to export files. For example, "exports" or "static"

Additional context
After static .html or .md files are exported to the folder, I will symlink that folder to my Dropbox website folder, that automatically serves the website through fast.io hosting.
