Hi, I'm glad you found it useful.

1. In quick mode, when you hover the cursor over the folder name and wait for some time, it shows popup for bookmark folder path. Do you suggest that the folder path below the folder name will be better?

2. Can you elaborate more on this? If I understood it correctly, does it mean to mimic the behavior of Ctrl+D in browsers? In this case, It can be used with "Open Add Bookmark Popup" shortcut binding which is set to 'Ctrl+Shift+A' as default, and it can be changed from extension shortcuts settings... In order for it work same as Ctrl + D, quick mode need to be enabled. Do you want the bookmark to save automatically to last saved folder directly when opening the extension popup?

3. By default no folder is selected, but when user hits enter key, it selects the first folder in the list and saves in that folder. Top 5 folders above the dashed line are recent 5 folders where bookmarks were saved earlier. So, by default, on hitting enter key the bookmark is saved in last bookmark folder itself.

4. Noted. I'll add a star in it's name or change highlight color to indicate that bookmark is already saved in the folder.

5. I thought about it, but the browser's native bookmark indicates whether the bookmark is saved or not, so I had decided to avoid it, since changing extension icon every time a tab switches, it will be unnecessary load on browser. Plus, the icon looked ugly with filled color :(. But, you're right, once user starts to rely on it, it is better to indicate somehow through the extension itself. I'll update it too..

6. Can you send me a screenshot for this one to x̶x̶x̶x̶@̶x̶x̶x̶x̶.x̶x̶x̶ ? I need to understand the reason for horizontal scrollbar. In my testing, I am not able to reproduce to fully understand the reason behind this. By any chance, is there any folder with very long name? I tried with really long folder name but it's working fine in my browser. A screenshot will be helpful to understand it fully.

Edit: New update published with all these features.
