Sadly I don't know anything about the pocket edition, so I can't really say anything about it. But I asked about it in the DWM Discord, so if anyone knows something about this, they will probably answer sometime. (Discord)
not sure if this is a problem on my end but i've tested it with fresh installs & i seem to be having a problem with the top of doors in certain orientations having missing textures, mind testing that for me?
XeroTrinity edited the colours a bit in his Dandelion X texture pack and edited some of Steelfeathers ( Her 1.12 pack ) original textures. He has a lot randomized textures and some pretty cool optifine features
Hallo89's DWM version supports a lot of mods. He updated the colours over the years and also supports a lot of randomized textures and made some custom models. Sadly DWM is only available for 1.13 as he currently doesn't really work on the pack ( but I'm sure it will be updated some time in the future)
My Dandelion Expanded or Dandelion + pack is probably the most complete dandelion version in the internet. It's really important for me that no of Steelfeathers's textures get lost or edited and I use her textures to make those which are missing. With the next update the pack will also support mods and a lot of randomized textures. At the moment it supports a few optifine features, however it'll get more with the next update. Basically the only missing textures are some of the entities, but we don't have seagrass or kelp yet and very few items are still place-holders, which will get final textures soon.
There is no perfect pack for 1.14.4 as every pack has its own style. You will have to take a look at each pack and decide for yourself which pack you like the most.
Besides these three packs there are a lot of other edits and the textures in the packs are made by many different people, not only by the four of us.
Of course I can say much more about my pack, as I use it all the time and I made it, so I am really quite sorry, if I missed anything (which I definitely did)^^
If I got anything wrong, please make sure to correct me, as everyone needs to get the credit they deserve!
