+### Description
+
+Based on the original remembertags patch by minego.
+This patch expects the pertag patch to be applied first.
+
+To quote from the original remembertags patch:
+
+> This patch modifies the behavior when selecting tags so that selecting a tag will also enable any other tags that were previously visible.
+>
+> For example:
+>
+> 1. Select tag 5, with mod+5
+> 2. Toggle tag 8, with ctrl+mod+8
+> 3. Select tag 1, with mod+1. Tags 5 and 8 should no longer be visible.
+> 4. Select tag 5 again, with mod+5. Tag 8 should be visible since it was remembered.
+> 5. Select tag 5 again, with mod_5. Selecting the already selected tag resets any remembered tags, so now tag 5 should be the only one visible.
+
+Remember to change `TAGCOUNT` to `(int)LENGTH(tags)` if you're also using bar patch.
