Sanskrit Language Tools

Toolbar with a) buttons to Sanskrit-related resources: Sanskrit news from India, online Sanskrit magazine, Wikipedia, and a few more., and b) grammatical tools (dictionary, verb/noun declinations, sandhi joiner).
Once installed, an icon (the Sanskrit 'sa' letter) will appear at the bottom right of the window. Clicking the icon toggles the toolbar's visibility.
Double click any word in the window and the word is copied to the input field in the toolbar. Select the appropriate tool from the Tools menu, fill in any additional information (verb look up requires the gaNa number; noun lookup requires the gender; sandhi lookup requires a second word), and click the submit button.
Some of the functionality here is repeated in the userscripts "Sanskrit Tools - Dictionary" and "Sanskrit Tools - Grammar".
