Some custom nodes and extensions aren't working on Colab

Hi. Thanks for developing ComfyUI. I'm having lots of fun using it. I'm experiencing some issues in Colab though:

1. I'd like to change a node's name, but clicking properties just closes the pop-up menu.

2. I get errors when using some nodes in Colab:

Cannot import /content/ComfyUI/custom_nodes/sampler_tonemap.py module for custom nodes: invalid character '·' (U+00B7) (sampler_tonemap.py, line 72)

Cannot import /content/ComfyUI/custom_nodes/sampler_rescalecfg.py module for custom nodes: invalid character '·' (U+00B7) (sampler_rescalecfg.py, line 72)

Cannot import /content/ComfyUI/custom_nodes/comfy_controlnet_preprocessors module for custom nodes: No module named 'mediapipe'
Traceback (most recent call last):
File "/content/ComfyUI/nodes.py", line 1304, in load_custom_node
module_spec.loader.exec_module(module)
File "", line 879, in exec_module
File "", line 1017, in get_code
File "", line 947, in source_to_code
File "", line 241, in _call_with_frames_removed

3. Then the image feed and node locking extensions aren't working. I also tried putting the .js files directly in the extensions folder but they still don't work. Here are all the additional lines I'm using in Colab:
