PDE enhancements - variable highlight + pop out console

Relevant sub-area for this feature?

PDE

Feature description

Hi there,
I would like to request some enhancements to the PDE.

1. When you click on a variable, it would be good to see on the right side of the scroll bar instances of the variable. Tabs containing the variables should also be highlighted.
   This feature is available in Matlab editor.
   Notepad++ has the highlighting but not the side bar.

2. The ability to pop out the console. This will be very helpful for people developing GUI connected to pieces of hardware (e.g. Arduino, NI-USB ...)

Benefits

The highlighting feature will allow an easy access to all lines containing a given variable.
The ability of the pop out the console will add convenience when debugging code using two monitors: one monitor for the GUI, the other monitor for the IDE and the console side by side.

Possible challenges

Would you like to work on the issue?

This should be easy to implement for someone familiar with the IDE development.

首先在 processing4 仓库中定位 PDE 编辑器和控制台的入口点。检查当前如何处理编辑器标签页、滚动条、变量高亮和控制台；完成的标准是两个请求的增强功能能够协同工作，同时不影响现有的 PDE 行为。
