 # Future Plans
 + [] Electra standard library
-+ [] Performance Improvements to brainfuck interpreter
-+ [] Test gmpxx's floats. Do some benchmarking and if it is suitable, use them to be able to store big numbers.
-+ [X] Code cleanup
-+ [] Add unit tests
+    - A standard library for electra for common tasks.
 + [] Visual Mode: See your code in action!
-+ [] Electra on the web
+    - I need to implement [yacw](https://github.com/DolphyWind/yacw) first, because there are no ncurses libraries for my needs. Which is unfortunately not gonna be soon, I have many things to do.
++ [] Electra on the web: Compile and run Electra code in the browser
+    - Either compile the code to webassembly or write another interpreter in javascript. Probably the former.
++ [X] Code cleanup
+
+# Cancelled
++ Performance Improvements to brainfuck interpreter
+    - I was planning to use two stacks to emulate a tape of a Turing machine, but the current implementation took a weekend to finish. If I find a random motivation, I might do it. But for now it is cancelled.
++ Test gmpxx's floats. Do some benchmarking and if it is suitable, use them to be able to store big numbers.
+    - I don't think this is overkill and not needed.
++ Add unit tests
+    - The project is quite stable already, and Electra is a toy language. I don't think it is necessary.
