Improve how variables are displayed in the title

Variables look kind of chaotic when they are changed into the name with the %20. For the variable with underscore it seems to be changed to lower case, and where as the single word variable is kept as the original upper case.

I do like keeping the path as the names to reduce book keeping of keeping names up to date, but this makes it a little less clean. Not sure what the best change/alternative would be, but i do really like the minimal ui/ux the app has so I'm sure you would come up with something sleek.
