1. A search box next to the URL bar.
2. Searching shortcuts. Like "g k meleon" to search Google for K-Meleon.
3. Ability to create search engines. For example, in Opera you can simply right click on any textbox in a form and create a search using the SUBMIT URL of that particular form.
In case you don't know, the URL bar doubles as a search box. Type in a word and press the search button for a Google search, right-click the button for further search engines.
To change the search engines use Advanced Preferences - Browsing - Finding Websites - Web Search, and Edit - Configuration - Search Engines to add any not already in the list.
Does anyone know if it's possible to have more than ten search engines for the search button and context menu?
