What do you want most in D&D Beyond?

I (used to) copy the spell information into a note or word-processing app, re-format if necessary, then print onto faux-vellum sheet so that it looks like a page out of a spell book, then give to the player for their character. In addition, this can be done for scrolls using the technique, but print SCROLL at the top and have the player give the DM back the sheet when the scroll is used. For rituals, just print RITUAL ONLY at the top instead of SCROLL. 

By the way, when it comes to RITUAL spells, I allow my player's character to prepare and perform ritual spells from a ritual spell book, but only if that ritual spell is a spell the character class could cast and at a level the character could cast, without counting as part of their list of spells known. Obviously this can only be done from a secure(d) location for the entire time of the ritual casting, such as in a bastion. (This was prior to the 2014 edition.)

To forget that aesthetics even exists and maximize all effort on functionality. Give us a more robust but well-guided homebrewing system that doesn't lock us into pre-cut concepts. As it is, I use Chat all the time to help me get through mechanical slog of my creation ideas. That also helps me with balance, because it can do math and apples to apples translations easily. Add a layer selector to stickers and tokens in maps along with some pre-built AOE and more robust condition marking options than plain colored rings.  Also allow users to add any images for stickers or token markers. Allow for token scale to shrink more against a map that can't get any bigger. That's all I've got this very moment.

Quote from CaptainSass >>

I have been DMing since about 2018 and went from playing mostly in person to online for the last few years to recently rediscovering pen-and-paper. I have a new game with almost entirely new players and I have outlawed laptops and tablets. Boy has that been a great decision for focus at the table! but it is a downside for my casters.

It would be great if some support could be given for the pen-and-paper crowd like printing out spells in their entirety rather than just the list of names like the current character sheet does. Or adding a PDF of the magic items/monsters to adventures so I can print the stat blocks I need without having to flip through my monster manual. Even book marked, if you have multiple monster types in your encounter, it's a little bit of a pain point where I find myself reducing encounter complexity to limit page flipping. Right now I'm screen shotting and printing everything but it would be great to just print the content I own (wouldnt even mind a massive water mark) for myself and my players that are specific to our adventures or in the case of spells, specific to the characters. Would be a massive quality of life update for my prep. 

 I've been using 5e-spellbook.app to build spell lists for new players who want to use paper.  But that doesn't include extra books etc.

GOAT- thanks for the tip, I'll try it!
