There's some legal restriction?
The general license for the Arduino IDE code is GPL v2.0, see:
but as artisticforge said, there are different licenses for other components and you'd need to evaluate them as well. If you're just wanting to tinker around with the IDE code for your own personal use then you have nothing to worry about. If you want to distribute the code you will need to make sure to comply with the licenses.
Also, if you want to submit what you've done as a new feature for everyone, you need to create a license for your code, e.g., GPL v2.0, plus conform to the procedures for submitting a new feature.
