◼ Overview
This is a demonstration of dual logging library I have ported from my personal use for public use. Please start bar replay from Bar#4, and progress automatically slowly or manually.You would need to go through 450+ bars to see the full capability.

Logger=A dual logging library for developers. Tradingview lacks logging capability. This library provided logging while developing your scripts and is to be used by developers when developing and debugging their scripts.
Using this library would potentially slow down you scripts. Hence, use this for debugging only. Once your code is as you would like it to be, remove the logging code.

◼︎ Usage (Console):
Console = A sleek single cell logging with a limit of 4096 characters. When you dont need a large logging capability.

Pine Script®

◼︎ Usage (Logx):
Logx = Multiple columns logging with a limit of 4096 characters each message. When you need to log large number of messages.

◼︎ Fields (with default settings)
  ▶︎ IsConsole         = True  Log will act as Console if true, otherwise it will act as Logx

v3 of Logger library released.
Demo code updated to reflect the changes in the library and showcase new features

Library Changes:
- Better error checking. Should not see anymore errors on usage now. I am using this for my debugging my other code developments and that has helped to thrash out issues from v1 and v2.
- Improvements to async logging
- Addition of individual coloring of cells when logging.
- Ability to revert logged messages (undoing messages)
- New overloaded functions for letting all types of calls to log/alog/page/logX/undo/undoQ/undoX
- Massive improvements to documentation.

Known Issues/Limitation:
- When using this library your script will compile for lot longer and may slow down as well. This should be ok, as long as you debug parts of code and move them to a final working version of the script. This library is just for debugging your code.
- The library itself is reaching the max compiled code limits on my development version.

Next Update:
- I will look to see if I can implement independent queues (logging 6 queues separately, not asynchronously.).
