No, it's not related to an issue.

Describe the solution you'd like

You know, when you play DDR on an Arcade cabinet or a pad at home with official Konami charts, they are designed to flow correctly. However, when making charts, currently, you need to know how make the chart flow according to the difficulty you are charting from your pad experience. So, if you always were a keyboard player that always played keyboard level of difficulties, it's really hard to imagine how you should dance the song. In the end, yout put random steps everywhere and it feels like spaghetti to an actual pad player.

So, to improve upon this, in a distant update, when the song is played in the editor, a pad with the feet (R) and (L) on them, will dance to the chart. If there are patterns that does not resolve, the indicator should warn the user and offer mutiple fixes. If techniques are charted, the graphics will also show them (Jack, crossovers, step-jumps, etc.). If a particular technique is introduced in a difficulty they shouldn't be involved (ie. fast 16th crossovers in beginner), the helper should triple verify with the user if they really sure if they want to do this. If not, they should also offer possibilities to fix the issue.

Additional context

DDR Patterns lingo: https://ddrguide.com/glossary/#group-patterns
(For some reason candles aren't listed, or maybe it's "lateral-crossovers")

A "How to execute song @ difficulty" video with the graphics I have in mind:

There could be a lot of ways to make this work: hardcode every single combinations. Ideally, you don't want to do that. The other way would be... training an AI. Training it so it recognize streams, jumps, hands, candles, jacks, patterns that doesn't resolve, etc. We could help that AI by making CHRS4LFE make chart and testing them versus its knowledge. If you guys don't know him, he's currently the current DDR champ. He's a living metronome. Look him up on YT.

Anyway. This initiative should be considered, if accepted to be coded, as part of redesigning the step editor. Because, let's be honnest... it's probably the most outdated portion of the game. I could write a novel about it.

P.S I already sent the suggestion on Discord and to Squirrel in DMs. I'm putting it here so you guys can remember about it and tag it if needed.
