<!--Hi! We prefilled this issue for you with things that should make this it easier for you to let us know what is going on. You can freely remove what is not necessary or add what is missing. Thanks! --> **Problem** <!--What problem does this solve? You can also reference another issue!. Ex. I'm always frustrated when [...]--> When I tried to compute a route for quite big data, my QGIS seems hanging. I don't know whether it's still running or just hanging. **Improvement** <!--How do you think the problem could be improved?--> Add a progress bar or busy cursor to indicate that it is indeed still running **Alternatives** <!--Maybe you thought about other ways to improve the problm and if you have an opinion on why that would be bad.--> Even better, if it can run in the background, so I can still use QGIS while waiting the computation. Thanks!
