You can change Settings > General Settings > Defaults > Song Duration and that will be applied to any new set lists you create. You can then override it for particular set lists on the set list details edit page if needed.

Ok, thanks. I'll have a watch. But that brings up another question/scenario.
So I don't really use setlists in the conventional sense. We play to the crowd in front of us, and we pull from a repertoire of several hundred songs. Id say over the course of 1000 gigs, I don't think I've used a structured setlist twice. Instead, what is important is being able to access a list of material to pull from (sometimes grouped by genre depending on the gig), and bring up lyrics/chords quickly, and be able to scroll them while performing.
:: Ideally, when I enter <<SONGS>>, I could access the lyrics/chord layout directly from there. No setlist required. Unless I'm missing something, this doesn't seem to be the case. ( I would love a button that next to the title that enters the lyric/chord view of my choice)
:: If I have to use setlist, I have to one by one add 300+ songs and then ensure that each new song we add gets manually added to that setlist of 'all the songs'. Failure to do so means that song will get overlooked in future gigs. We add material even during a gig, so we are often under pressure and things get missed. Seems a lot of maintenance just to access a list of all the songs.
:: If I use smartlist, I don't seem to be able to enter a default duration, so nothing scrolls.
What do you think the best approach is there to achieve the desired setup?
Also, just a side note on the scroll/duration issue:
I really like the product. You've done a great job and I'm looking forward to making it the go to tool at my gigs

However, the scroll issue seems to pop up a considerable amount in the search, and seems to be a barrier to quick entry for some. I think that is because there doesn't seem to be any logical relationship between the duration of the song, and whether or not , and how fast/slow, it scrolls on the page. This is purely an software engineering concern that from a UX perspective should be invisible to the user. I've used other apps (greatly inferior to this one in most every other way) that had a simple scroll speed + and -, and whose value was stored. Simple and effective. Changed as needed. If I played a song faster, I increased. Decreased if slow, etc. I'm not sure what is gained by forcing the scrolling capability and parameters to the duration of the song, but it seems only to add complexity and unnecessary maintenance of data. It occurs to me that it might have something to do with its reliance on the layouts, which seems to use fixed values for dimensions, and hence don't translate well across devices. Could the issue be solved by making the layouts dimensions relative, which should fix cross device layout compatibility and the need to have layout dependent scrolling?
Hope you don't take offence to my suggestion. I only want to help improve the product in a manner that suits my own selfish needs
