It would be nice to be able to customise the display to reduce margins and spacing to cram more in on the page without reducing font size when necessary.

I prefer a smaller header, and like to put dates and page numbers on the footer. While this can be achieved once the Word document is created, it would be nice to set up a default template rather than having to do it for each individual export

It would be very useful to me and my band to be able to add notes to songs, e.g. about arrangement. This could be done on the set-list level (maybe additionally on the song level, too?). Or to make this even more flexible: Some sort of key-value annotations? I can think about some usecases like tempo, songbook numbers, etc.

Those notes can be displayed in smaller / different font along the song text.

Add a field to control presentation order (like opensong). For example, sections are labelled with [V1] [V2] [C]. Each section only needs to be shown once in the song text area. A separate setting controls the display order and can be changed when displaying the song. A song with the above structures could be presented like this v1 V2 C C V2 C.

I use opensong primarily which has a very well defined format for chords etc. I would like to be able to export to chordle for use on a portable device. One great feature of opensong is to define the presentation order. Like many others, including ultimate guitar, it also uses a monospace font. I have written a powershell script that converts the format, but I still have to use the monospace tool in chordle for each song.

E.g. in english I would like to have "Interlude" and in german "Vers" "Strophe" "Refrain" "Zwischenteil" "Ende"
You could give opportunity to define more titles or implement more for all users

Would be great to add a song's duration that can be used when creating set lists to estimate the timing of the set - if you're doing three 45 minute sets, would be great to be able to drag/drop songs to the set list and have a time total at the bottom.

Being able to sort, order, and arrange set lists by alphabetical title, composer, artist, Tags, or other metadata would be a nice feature to add. Also, being able to save an otherwise non-ordered list so you could switch back to it after the list had been otherwise ordered (such as alphabetical) would be a definite plus. I have found that I sometimes arrange a set alphabetically when practicing or editing, but an option to re-order back to a saved order would be excellent!

Show the current key in the song edit screen so if i need to make a quick adjustment and we are not playing in original key i don't have to do a bunch of transposition.
Secondly to this would be good to have the Roman Numeral notation available as a key.

Attach YouTube video to a particular song for reference

When in edit mode, the right pane splits the edit and display window and is adjustable. However, the Left (song title) pane does not adjust which makes it difficult sometimes to view details in a title. The left pane should adjust as well.

It would be very helpful to have lists of our created setlists...In that way we can have the whole 'act' in one single list...containing the other lists!!
We won't have to search the next list to be played...it would be waiting as the next list!!!

develop the software to do this would be usefull

It not usefull to see all song import success in one new popup and refershing list view of ll songs take a long time - maybe is it better to refresh the list only when the import is finished (I have a lot of file to import).

Maybe like in the Win-App "Chord Chart" (I find chordle the better App, but in this point Chord Chart is easyer to use), where one can select a chord by finger or mouse and move it wherever it is needed.
