Just a feature request:
Without SSH access there is no way (as far as I know) how to run october:migrate from backend (only as side effect of force update).
In OC4 there are buttons in Settings > Software Updates > Manage Plugins that can run cache:clear and plugin:refresh.
It would be great if there is also an october:migrate option.
you can build a url to trigger a command.
something like /commands/october-migrate that would trigger the command php artisan october:migrate.
I think there was a plugin existing in the past which was doing something similar to run specific command from the url.
of course, you would need to apply some security.
Hi @chris and thank you - I know about that (it is plugin by Vojta Svoboda).
This is just a proposal to add a one last missing piece in the backend 
Best regards,
Jan
