Thanks for the input!
To clarify, the idea is:
Now, you have a item on the menu to click and this will run whatever command it mean to run, such as a plugin or opening a browser.
My idea is, instead of having a text with a name (like all entries on IJ menu), I would have a search button with a text field. When the user clicks the search button, it will be pointed to the webpage with the search results.
In that sense, the idea might be really close to the Search Bar. I’ll take a look into that and see if it fits.
