I did not fully grasp the power of tags until I started working more seriously with Zotero. It would be great if raindrop.io could support a similar filtering functionality.
When filtering based on a specific tag, the list of available tags would be reduced to only contain the tags contained by the filtered bookmarks.
For example, I currently have a total of 150 tags in the left pane. If I select any one tag, the list of tags does not change and it still maintains the same 150 tags, even though the filtered bookmarks do not contain all of them. It would be great if when one selects a tag, the list of tags gets filtered to contain only tags present in the filtered bookmarks. The Tag list would then get filtered down to a smaller number and would continue to filter down as additional tags are selected in the filtering process.
