I use Emacs for literally everything. - plaintext (vCard) and org files for CRM and opportunity management (with lots of Elisp to find information, GDPR-compliance, ...) - mu4e for email - ledger for finances - org-mode for calendar, project management and time-tracking - org-mode for task management (I have one big TODO list sorted by priority, every task gets an estimate number from 1..10 for required effort and importance, from which a priority is calculated; I never think about what to do next, but just work through the list from top to bottom) - Elisp for rapid prototyping and exploring a problem space - org-mode, org-babel and lsp-mode for development & documentation - magit for version control - LuaLaTeX templates for invoices, letters and other document-form communication (Emacs replaces placeholders with values, then generates a PDF) Side note: I heavily reshaped org-mode for my needs, for example redefining internal functions and a lot of other hacks. I love Emacs for giving me this freedom and flexibility. The PROPERTIES drawer for org headings is also great to store custom IDs. This way you can link stuff across multiple files and folders.
