Reportei is a beautiful tool and saves me tons of time when I need a birds-eye view on all my marketing campaigns and metrics. Obviously, you'll want to dive into your native platform dashboards for more granular details but Reportei works great as "reporting at a glance". For the most part, there are very few bugs that I've encountered (nothing major at least) but there are a few features and details missing that I think would take it up a notch.

💃 The Yay
✔️ beautiful UI
✔️ accurate reporting
✔️ easy public linking to reports
✔️ easy to set up reports, dashboards, and automation

🙅 The nay
❌ non-native English dashboard - window titles and email notifications are in Portuguese. Google translate does this, but still.
❌ no differentiation in automated report emails - each email subject is the same ("Seu relatório automatizado foi gerado com sucesso") and it does not tell you which report is being sent to you. I'd like to see it mention the title of the report we set during the automated report setup.
❌ limited metrics and column customization (no CTR on a keyword level)
you can't add new ad groups from an existing one, you need to add a new campaign and remove the old one

🥺 Feature requests
❤️ better note-taking, perhaps as an extension of a module with the option as a standalone content module
❤️ name report/dashboard at creation
❤️ edit/delete/rename/duplicate reports/dashboard from client area
❤️ CTR column for keyword summary metric
❤️ Analysis period shortcuts (ie. today, yesterday, last 7 days, last /2/4/8/12 week(s))
exclude keywords based on campaign visibility
❤️ native English website, email notifications for automated reports
❤️ template name as the title (ie. copy of template name)
❤️ undo icon next to update dashboard instead of the yellow banner
❤️ make predefined metrics list adapt to screen, not making good use of side navigation real estate
