@Max Derksen (Derksen) Maybe there is also an option for saving the shortcuts in the workaround. Just check keys.py in snap utilities.
I am an add-on developer and faced the same issue in my tool. I got the pointer about this workaround from one of the users (thanks @yoshiki nosaka (sakana3)).

Hi @Max Derksen (Derksen) , if you are looking for a workaound for the problem of custom tools not working on Blender restart, you will find it in addons/mesh_snap_utilities_line/__init__.py
A simplified version of it is in: https://raw.githubusercontent.com/Shriinivas/blenderbezierutils/master/blenderbezierutils.py
(Essentially, you would need to register the tool and keymap in some roundabout way)

Sure, I will upload the diff.
I haven't done it so far. So it would help if you could let me know the process. Or maybe the link to a wiki that explains it.

Attaching the file with the change.
Also uncommented the functions.

I think line # 392 (in unposeMesh) should be:

Hi, it's an importer by itself. The add-on uses svgpathtools (https://pypi.org/project/svgpathtools/), an open source python svg library to do the parsing etc.

Hi, https://blender.chat/home works, thank you! My chat handle is Khemadeva. Hope to meet you there some time.

The artifacts are maybe because the text curves are 2d. If you make the curves 3d probably (not sure though) they would go away. Thank you for the feedback :)
I tried connecting to the chat URL, but am unable to access it from the web browser (Firefox / Linux). Do I need a separate chat client?
Or maybe I should put this problem on forum.

I have committed these changes. Also moved the entire UI logic to the bottom so that the related parts are all together. Hope this is OK.
Thank you for doing this , actually I should have checked for the trailing spaces before the intial commit.

Hello, I got the commit access to the repository today. Thank you!
Please let me know whether I can commit the add-on script (in release/scripts/addons?).

Great.
Yes, I will make sure the add-on remains intact with the new changes in 2.8 code.
And I will be happy to maintain the code within Blender repository. Kindly let me know what I need to do next, apart from going through the Wiki pages you've given.

Thank you!
Do let me know if you have any suggestions or queries with regard to the code.

I appreciate your taking the time to have a look at the add-on.
Do let me know if you need any further code-specific information from me or have any suggestions.

Thank you for the update. I look forward to your testing outcome
