Here's some quick issues and suggestions I found after about 5 minutes of playing around with it. All test were done using Firefox FYI.

1. One of my favorite features from the built in DuckDB UI is the panel that automatically generates graphs for each column, both for the whole dataset itself and for the specific query you're running. I often find myself not even writing any queries because all I needed was something really simple already available in that panel. This would be my #1 reason for not using this GUI instead of the built in one.

2. I could not find any panel to show the currently selected value in the grid view. Ideally I would like this to also be able to auto-detect common formats like JSON and format them, etc.

3. The grid view can show a maximum of 200 rows. Finding a way to virtually render the rows in an infinite list would be much better IMO. I've found myself selecting up to 10k+ rows in the built in GUI and to copy all IDs, etc, several times (saves sometime compared to exporting a CSV and copying from there).

4. The column filter dropdown in the grid view has a search bar which is nice, but it is automatically deselected on each character entry, making it very annoying to use...

5. Additionally the dropdown filter menus are not automatically closed when you click outside or open another dropdown, which is a minor annoyance.

6. The right click menu in the grid viewer will close on "mouse out", however it does not close on "click outside" and the cursor does not start inside of the menu itself. This means the menu becomes permanently stuck until hover over it if you immediately move the mouse to the top-right on open.

7. The grid view resizer is behaving buggy sometimes after changing the number of page rows to display.

8. The transparent tooltip background in the chart viewer makes the light-gray text impossible to read in dark-mode when there is yellow behind it (from other the chart bars).

9. The explorer side panel seems to be sized based on a percentage of the window size. this is quite minor but it would behave nicer if it had a fixed size so changing the window size does not also resize the side panel. It is also overly large when you first load the site.
