Improve drag-and-drop playlist implementation

[Borewit]

Improved drag-and-drop behavior:

• Allows to drag playlists on playlist-editor, when no playlists are opened yet
• Allows to drag playlist into another playlists, or if opened as a new playlist
• Allows to to drag a playlist as a new tab

Debt:

• Remove redundant code

Technical debt remaining:

• Dragging a playlist is now converted as M3U with corresponding MIME-type, instead of proprietary string. Yet needs much refinement. Dragging entries from one playlist to another will not work correctly.

Depends on io.github:borewit:lizzy:1.2.0

Thanks, I am onto it.

Testing: listFix_2.6.0-PR136-29.exe

Improved drag-and-drop behavior:

* Allows to drag playlists on playlist-editor, when no playlists are opened yet ✔️ 

---

* Allows to drag playlist into another playlists, or if opened as a new playlist ✔️

---

* Allows to to drag a playlist as a new tab ❓ 

Not sure what you mean by this?

ℹ️ What is missing, is support for dragging playlists from folders in the PLD, to dropping it into the PLE.

Allows to to drag a playlist as a new tab

Be able to drag in a playlist like this, (the visualization may deviate)

Yes I did, I agree with that. Better one solid theme, than 5 which are so so. There are still so many area's this application could improve. Sometimes I don't know where to start. I want to give JavaFx a try to see if that is doable and maybe a better investment for the future. But also also would like to utilize Lizzy better, to concentrate all the playlist functionality in there. Currently it is only used for iTunes playlists. And to distribute ListFix an AppImage.

I cannot test this just now, to figure it out. Probably, tomorrow. How does it differ from the first item on your list: "Allows to drag playlists on playlist-editor,..."?

About the Themes: We agree then. However, on having second thoughts, it might be worthwhile to consider retaining just one dark theme along with light default. Should I go ahead and post the proposed theme modification as an issue/improvement?

You have made extremely good progress, and we already have a functional app, where a short time ago we had no such thing Therefore, don't worry too much, and do not try to do too many things at a time. Stick to ticking off the "boxes" like you're doing now, and just keep your focus, and the pace, steady.

Although I do not know the first thing about programming/coding, I really want to assist you, by helping you to determine some of the listFix() priorities from a user point of view. For instance, I think the next in line for your attention should be saving the current layout (or session) upon closing the app, because it's such a drag on the user having to start over before commencing to edit again, a previously abandoned, incomplete session.

Dragging the playlist to this location will assume the playlists should be opened, as it is not dragged into another playlist

Let's postpone the detailed visual improvements, I started playing with JavaFX, I may redo the entire GUI. Will take a bit of time, it's like 4000 km journey by foot.

I can make some progress in that area.

OK, then I have tested this too, already, and found it is working perfectly well just like the other two drag and drop operations. A full score!

Yes, from a practicality point of view, the GUI is not so important at all, unless it interferes with operations.

Let me know if there perhaps is something specific you want me to look out for in this test build?

BTW, is it purely coincidental, or have you done some work to improve the PLAY-button display: Select Best Mach / Preview / PLAY upon changes to the font style & size? Though anomalies are still visible when applying larger text, there appears to be a discernible improvement around the more commonly used font sizes.
