Suggestion: IITC plugin to extract basic portal data #29
Description
There already exists an IITC plugin that on its own implements a very limited "max fields" behaviour, so the data is certainly there[1].
Just would need a similar extension that either did manual input of portals via selection, or simply using "The current viewport". The first of those limits what portals you can include by requiring a click-scan behaviour, but can easily be extended beyond a viewport size and won't be limited by portal visibility settings. The second of which is more convenient, but can exclude important portals due to the zoom limits.
This would also be able to tie in nicely with #17 once it is worked out how, in that IITC could help garner what links, fields and link-directions are already present to factor in, and that would also reduce any queries you have to do yourself to google's servers to determine that data
It would also be a good place to assign agents to keys, because it would be a simple case of going "click as agent #1", then clicking Agent1's portals, etc.
1: As to why I'm just not using that plugin, its nowhere near as useful as maxfields is, and doing the heavy lifting in the browser is just bad design imho, because browsers are not very specialised at solving those sorts of problems.
