So to me this method in the long run might have it's issues but will keep an eye on it. A lot will have to do with how Pi-Apps implements updates as to if the updates will cause the terminal to not to work or not.
For me tho I will stick to the method I explained here: • PyCharm Install on Raspberry Pi with ...
But will certainly keep an eye on the demo Pi I have it installed with Pi-Apps.
you can head over to https://github.com/Botspot/pi-apps
to get the instructions to how to install there is a one line script that should do all the work for you there as well.
I thought I would get further on my previous project but was running late in the week here so thought what could I do and noticed I never covered the Pi-Apps install method.
