Generate Alignment Links within Tolerance should, optionally, only work in map extent

[SeanLyons]

The generate alignment links within tolerance option is an efficient way to automatically generate parcel alignment links; however, it would be beneficial to have an optional checkbox that would allow you to specify to generate links only within the map extent. This option would allow you to have more control over where links are automatically generated.

Say there is an area you are aligning where the links to create are quite obvious, but there is another area where you would be better off manually creating links. This option would allow that to be a smooth process.

How would you know upfront which areas require manual links and which areas do not?

And if you did know, wouldn't it be more efficient to align the 'manual' areas using the Align Features tool?

Or maybe we should understand the use cases for 'manual link creation' and try to eliminate them (and/or convey there is an issue in those areas)?

I won't know right off what areas require manual links but I wanted to use the Generate Links within Tolerance on smaller areas similar to how the Auto Join feature works in Desktop so I have some level of control over how many alignment links it is creating. It is incredibly difficult to use Generate Links on a larger plan to then have to confirm the links are correct. It can generate hundreds of links and anchors that require checking and that is to hard to do on large areas. 

The align features tool is not performant enough to use right now(Sarah is messaging Tim about this). It is also not great to have to split the alignment process into two separate pieces as it gets very difficult to confirm what you have and have not aligned.

An example of why I want windowed selection would be I have a large parcel that is near a control which has hundreds of connection lines coming to it. With the Generate links within tolerance that is creating hundreds of anchors where the connection lines cross the parcel. I have often had these anchors cause lines to warp where the anchors crosses if the rest of the parcel is moving. Which means I have to go through and manually confirm which anchors are valid and which are not. Most of the situations where we are trying to use the generate links within tolerance the links are also very short which require zooming in to quite low scale to add the alignment link (my other idea for the box tool comes from this).
