Quick update: In addition to the improvements in recent updates we're planning to

+ improve the overall performance of the tool, and
+ improve control over the specific tracks that are used for closing the gap. (no functional tracks, only from stock, etc)

Just as a general note:
We still have a number of significant improvements scheduled for the Close Gap function, as always it's just a matter of resources..

That doesn't make much sense, agreed.
Switching the app won't cancel the various functions starting with the next update!

> Often, the alternatives don't actually get displayed on the layout.

Sounds like a bug - does this always happen for you?
Couldn't replicate previews not showing locally..

The main problem with the close gap feature right now is that it's clunky to use:
- To start it, you have to go to another part of the screen, or press two keys on the keyboard.
- The animation showing all the points takes a few hundred milliseconds and is distracting.
- Once you click the first point, the whole layout shifts down, and you have to wait another few hundred milliseconds, as the UI pops in at the top.
- If you cancel it, or if it fails to find anything, you have to dismiss an annoying dialog.
- If you do anything at all while it's working in the background, you end up accidentally canceling it. It'd be nice to be able to edit unrelated things while it's running.
- If you switch to another application while the list is up, it goes away, and you have to do the whole process again.
- Often, the alternatives don't actually get displayed on the layout. Sometimes they do, so I assume they are always supposed to. It'd be useful if they did.
- The results aren't cached. I suspect the whole feature could be massively faster if you cached all computations persistently to disk. I often try to fill in the same kinds of gaps since I'm usually using the same track set with similar geometries. If we've computed the results once, let's keep them around for later.

This is already possible in the local settings dialog (accessible via the Gear icon) - Cheers!

It would also be nice to have the option in this to set the number of tracks that can be used, currently it is 5, where sometimes 7 or 8 straight tracks for example can close the gap easily.

1. Drag pointer across gap to select.
2. Fit with the fewest largest pieces available.
3 Show alternatives to select from.
4. Add a force fit feature to close small gaps that the actual track tolerates.

Thanks for the feedback - would you care to elaborate?
How would the app automatically pick one of potentially hundreds of possibilities?

Cheers!
