Hey Kosta, thanks for the kind words and for the detailed feedback!
Here's what I found on each of these:
1. Freeze columns in pivot tables - we have an open issue for this:
https://github.com/lightdash/lightdash/issues/5908. It's on our radar but not yet scheduled. I'll add a +1 for you.
2. Row totals summing subtotals - good catch, I've created an issue for this here:
https://github.com/lightdash/lightdash/issues/21068
3. Grouping rows without subtotals - same here, the new issue is available here:
https://github.com/lightdash/lightdash/issues/21069
4. Dynamic compact number format - I see you already created
https://github.com/lightdash/lightdash/issues/20651 for this, nice one! We'll track it from there. Someone else also suggested a similar thing, and that convo was tagged in the issue, but it's an internal slack channel, so you won't be able to see it.
We made some backend changes to how pivoting works in the application which were due for a long time, that should enable us to work on the features above at some point. To be transparent, none of them are on the immediate roadmap, but as that changes, you'll get updates here.
Thanks again for taking the time to share these!
