1. Can you change where the command palette shows up in Sublime? In emacs (M-x is our Command Palette) I can not show it, I can show it as a full width pane that takes up 50% of the screen, or I could recreate the Sublime Text look and feel (top of the screen X width, Y height). This looks like a toy example but I'm trying to show that there is not a single part of emacs I don't have control over.
2. Okay how would you do the following in sublime;
Your company is getting into credit checking. As such you now are beholden to certain rules and regulations around the safety of your code, and now your product owners want an update every time CreditCheck.java is modified by someone. They want to be notified in a Slack channel and also by email. They don't care if the top 30 lines are changed, but anything after that is important.
In emacs, I would make a hook for CreditCheck.java that any time I saved the file, it would run through the changes, check if there is a diff from line 31 onwards, and if so send a slack notification and send-mail the diff to the product owners.
I would just open my settings.org file and add the emacs-lisp to do this and I wouldn't even need to restart to avail of it - I could just load-file and have it working. All within emacs. You could do this via a tangle of shell commands sure - but emacs lets you do it emacs-lisp with ease.
Programming in the real world is full of stupid like processes like this, and emacs makes it easy to accommodate them. (Not saying that you should accommodate them, but the real world can be messy)
