yeah, my understand (from other readings over the last year) is that the drag-and-drop method of installing plugins to node, will work but isn’t recommended, and instead the “add files to the filesystem and meddle with the tiddlywiki.info file manually (don’t make any syntax errors!) and then restart node” … is the recommended way. I’m not sure why, since it just feels like a lot of extra effort just to be less flexible compared to doing things the same as single-file TW. (I assume there is some reason (perhaps it makes sense for more complex setups than mine?), but I’ve not found it in any doco I’ve seen)
relevant tangent: it’s worth keeping a single-file version of TW around so you can search for plugins, since the documentation for installing plugins on Node (https://tiddlywiki.com/#Installing%20official%20plugins%20on%20Node.js) says
Identify the plugins you want to install using the Plugins tab of ControlPanel
However within a node TW, that tab says
The official plugin library is disabled when using the client-server configuration.
…making it impossible to search the official plugin library from Node
