This extension is quite high quality in many ways. But the fact that the manually selected area cannot be increased if necessary after the preview is a major shortcoming. Wereas this can be done easily in AdGuard and AdBlock.

If this problem is solved, it will be great.

I didn't know I could expand the area I chose to block by clicking on the list of cosmetic filters, after the preview; Thank you very much for your explanation below.

I think many users like me are not aware of the feature you described below even if they have been using your extension for a long time.

Therefore, in the dialog box that opens in interactive element picker mode, it would be easier and more convenient if there was a scroll bar instead of a "Cosmetic filter list" to expand the area to be blocked.

In the meantime, I think it would be more useful if the location of the dialog box opened in interactive mode could be changed by drag-and-drop.
