allow user created flags
i would like to be able to place a flag (many flags) throughout my readings that will remain there until they are personally removed. the purpose of the flag would be a hyperlink to other locations within other resources. like a personal hyperlink to other material. this would greatly improve my ability to continue on a thought path and yet allow me to create digression if i so desired.
example - as i am reading in John 20:9 i could place "flag#987a" there and at any point in the future it would instantly link me to "flag#987b" in "Matthew Henry's commentary on the whole Bible" at the 3rd word in the 4th paragraph of the 20th chapter of the book of John within that commentary or where ever i place that flag.
this would greatly improve my ability to flow from thought to thought when presenting information or for absorbing biblical wisdom during any study.
