 # Plans for Webservices App
 
-High priority:
+I've got quite a few plans for this app... here's a rough sketch of what I'm planning.
+
+First release:
 
 * filtering of all properties like Categories, Analogues, Licenses, Statuses, Hosts, and Affiliations.
+* modal showing each technology in more detail. DONE
+* split out all constants (arrays) into separate files. ~DONE
+* split out functions into svelte components.
+
+Future versions:
+
+* upgrade to Svelte 5
 * a 'Technology' view (overlay), addressable by URL (i.e. going to, say, http://localhost:5173/ServiceName brings up the site with ServiceName shown in 'Technology' view, allowing people to reference a specific technology of interest to others).
-* split out all constants (arrays) into separate files.
-* split out functions into svelte modules.
+* ability to go 'prev' or 'next' in modals within filtered set of technologies.
+* ability to select a Hosts and view all Technologies with instances on that Host
+* ability to see the status (via UptimeKuma API) of each instance.
+
+Possibly, eventually:
+
+* move data into a database (rather than a fragile hand-crafted JSON file) with integrity checking.
+* Authentication for administration
+* CRUD interface for Technologies, Licenses, Hosts, and Affiliations.
