>>7127104>>7127110to clarify, most of the functionality you're looking for is there, the architecture is just a little different.
I wrote a custom filesystem that uses the browser's local storage, so you can save files but they don't persist across machines.
you can save a bookmark by just putting [site name] [site url] on separate lines in a file called ".bookmarks" and enter its name to go there.
for shortcuts:
entering "/g/" or "/g" would just take you to /g/
typing a query and then ending it with a flag searches the website for that query, for example:
"can you a power a boat using only magnets? -g" would search google for that, and ending with "-y" or "-w" would search youtube or wikipedia.
there's other stuff like weather, and you can also write your own functions.
