Most reviewers are giving importance to improving the UI/UX more. Because Samudai can do so many things, the information put in front of you as end-user is a little overwhelming.
Part of the suggestions is offering users the ability to customize their dashboard according to their preferences. Also minor adjustments to the UI.
Another suggestion for improvement is more about adding more tools and capabilities to Samudai (although this talks about how users relly like what they saw, and will like to see more tools that they use in other DAOs to be added to Samudai).
i.e. Adding voting capabilities inside Samudai to allow for voting in Grants proposals.
Better notification & communication mechanisms. Cosmetic improvements to the UI, and enhancements to UX. Mobile support seems to be a very interesting point for many. It can still use a bit more simplicity in how information is presented to the user. From the numbers in a more human-readable format to the words used and even the font size.
