During POC, using wiki-in-iframe might be enough, yet wiki has number of usability issues for our case of “documentation on tips of your fingers”. Here are random notes on dedicated frontend:

HUD visualsation notes:

• Context links scroll from bottom to up, 5 last are shown
• Сontexts are clickable, expandable to corresponding F1Memo
  • keyboard focus is at that F1Memo
  • cursor location is at the same spot the user left it at last edit
  • autosave
• Contexts that have no F1Memo are on the right. Contexts with F1Memo are on the left
• F1Memo screen can be split into two, with “active” on left and “standby” on right
  • Pressing ESC would cause the F1Memo to disappear (and “Close” to become back “Edit”)
  • If the user never opened the F1Memo, then popup is pushed (once)
  • If someone edited the F1Memo, then its link has “new” sign
    • Updated Memo has button “Proofread”. In that mode there is additional column on left that shows diff status. Changed lines have “zoom glass with red question mark inside” mark. As user moves cursor off the changed line, the question mark in zoom glass becomes green V sign, and disappears after a second. If there still are “unreviewed” changes above or below, then on top or bottom of the “diff status” column there appears arrow with smaller “zoom glass with ? mark”. Clicking on these would jump the text, so next changed line is in the middle of text area.
  • Other users, as they get into the context, will see that the Memo was changed, again, with popup (once) and “Proofread” button
