Steem-Engine is a great tool. However, there is one important feature I think should be implemented. It would have saved me a lot of time and trouble.
The Engine
Steem-Engine has really proved its name worthy. Ever since it was released, the Steem blockchain has been buzzing.New tokens, new (niche) platforms... the options seem to be unlimited.
It has become the backbone of Steem tokenization.
The Missing PAL
No matter how great it is, the fact that there is a piece of the puzzle missing has been giving me a severe headache for more than a week.

Managing the Voting Power of Multiple Staked Tokens - 2
I thought it was a great idea to delegate the major part of your tokens to a different account, so you wouldn't be draining the VP of your main account all the time.
I must say, it works like a charm.
BUT...
I had delegated 1000 PAL to an alt-account, or so I thought.
When I wanted to undelegate, the popup told me I delegated 2000 PAL. Strange, because I could only undelegate 1000 PAL from my alt-account.
I didn't have a clue where the other 1000 PAL had gone.
When trying to retract a delegation, you need to enter the account name of the person you delegated to.
Sorry, can't show you the original picture, nor the one from PAL, since I'm still waiting for the delegation to return. For example purposes, I used the popup to undelegate the GG token.
I didn't have a clue to which account I delegated that 1000 PAL, so there was no way I could enter a name in that field.
The Search
I had gone through the list of my transaction using the explorer (https://steem-engine.rocks/), but couldn't find anything.
I visited the Steem-Engine account of every single account I own, but since delegated tokens are not shown in these accounts, this was pretty useless.
Today, I decided to use the explorer one more time. Fortunately, my transaction history only takes up 8 pages, and soon I found out I simply overlooked the transaction where I delegated 1000 PAL to a wrong account.
Imagine how much time this would have taken up if my transaction history would have been 30, or even 300 pages long...
The Missing Pieces
Personally, I think there are two features that would really make Steem-Engine even better than it already is. It might be that 
The Features:
1 - An easy way to see who you delegated tokens to.
2 - A way to see how many tokens have been delegated to an account, from within the dashboard of the account the tokens have been delegated to.
I think this would take away a lot of my confusion...
Also, it is not clear to me if upping to a delegation works like on Steemit, where you just send the full amount you want to delegate, or if you can just add to an existing delegation bit by bit.
Maybe someone can shine a little light on this? I would really appreciate it.
