Hi Suhail,
Looking forward to seeing the new version - the exposure curation tool has a lot of potential! 
I have many specific thoughts, but in general the UI needs to be greatly simplified, and optimized for larger datasets - currently it gets incredibly laggy and crash-prone with datasets of several thousand mics.
The little toolbar up the top of the right hand panel is very confusing and IMO mostly unnecessary - every time I use it I have to think about whether I want to accept/reject all, accept/reject selection, save, or “save and done” (?). The utility of these different options is not clearly apparent (why would I want to “accept all” when I am curating exposures?).
The text entry boxes for parameters should work - currently the user can enter values but nothing happens - only the sliders work. This makes it hard to adjust parameters precisely, particularly as the sliders themselves are quite laggy/jerky with large datasets.
Also, the drop down for selecting parameters to plot in the graph should show the full name of each parameter - currently it only shows the first several characters, which makes it very hard to determine what I am picking (without hovering to wait for a tooltip to appear).
The parameter graph also takes up a lot more screen real estate than it needs to, in my opinion - I wonder whether it would be possible to show both the overall and indivdual views side by side, to allow easy exploration of parameters - e.g. clicking on mics with different CTF fit res or motion correction stats and seeing the mic/CTF on the right hand side would be great. I would also simplify the zooming/manipulation tools in the param graph - adjustment of axes is all one really needs here.
I also wonder if maybe, given the number of parameters that are now present, it would be better to only show adjustment sliders/boxes for the parameters that are currently plotted, rather than showing all the undisplayed params also.
Cheers
Oli
