Similarly, other 'store plugins' rely on the search capabilities of the store they're querying (through OpenSearch or parsing the web search results). As Ive been using Calibre more, I slowly have been making use of plugins and wanted to share the few I use the most, and see if anyone else has suggestions that make their library management better in ways that we all might benefit from. Here's what I found so far: the above-mentioned store plugin refers to 's OpenSearch XML which provides a 'search URL': Builtin actions include: (1) Search and Replace, (2) Single Field Edit, (3) Calibre Actions, (4) Open With, (5) Copy to Clipboard, (6) Formulas. You can choose from builtin actions, Calibre interface actions, or custom actions created in the plugin's module editor. Looking also at the code complexity, I think there should be an easier way than converting the OPDS plugin into a store plugin. Connect multiple actions into chains that run from a menu or a keyboard shortcut. It seems that the former implements what the latter calls from various .* modules. Thanks David and Chris for the suggestions! I've been comparing the relevant parts of the OPDS plugin and an example Calibre store plugin.
