make it configurable how far away from the cursor the tooltips appear
the tooltip is very (very!) frequently in the way of typing in code.
first of all, the tooltip should NEVER obscure the cursor (it should just move out of the way), and, to ensure it doesn't have to move out of the way too often, make it appear near-ish (not near) the cursor. Like a couple of lines below the current position of the cursor, so you at least have a few lines of respite, before having to press esc to get rid of that annoying tooltip
