Recently I've been dealing with delegation a lot, and it's a real pain in the ass to manage! Vessel is a really great tool (many thanks to 
As a result, I've decided it's about time to create a web-based delegation manager tool to help everyone manage their delegations more effectively. Rather than create a separate website / project just for this, I have decided to add it as another tool within the Steem Bot Tracker website which I already run and maintain.
So without further ado, I give you the Steem Power Delegation Manager! You can access it by clicking the link in the previous sentence or within the "Tools" dropdown menu on the Steem Bot Tracker site.
As you can see from the above screenshot, you simply enter your Steem account name and it will load all of your existing delegations with options to remove or update them. If you have already logged in with SteemConnect then it will pre-fill your account name and load your delegations automatically.
Just below the list of existing delegations there is also a section where you can add a new delegation. You can simply fill in the account to which you would like to delegate and the amount of Steem Power you would like to delegate and then click the "Delegate!" button which will take you to a SteemConnect page to complete your delegation.
Additionally it shows how much SP you have available in your account to delegate (minus 6 SP to make sure you don't delegate too much!) and an easy option to delegate the max amount if you wish.
Last, but not least, if you want to give someone a link to delegate to a specific account, currently you can do that through SteemConnect, but you have to specify the exact amount of SP (in VESTS) that should be delegated and there's no way for the user of the link to change that other than updating the amount of VESTS in the URL.
Now you can instead provide a link to this delegation manager tool instead like so:
https://steembottracker.com/delegation.html?delegatee=postpromoter&amount=1000
This will default the "amount" field to 1,000 SP, however the user of the link can easily change it to whatever they would like. You can also leave out the "amount" parameter altogether and they will need to specify the amount.
I have a couple of future updates planned for this tool including:
@postpromoter bot, for example.As always I want to thank everyone who has helped and supported me in my work on the Steem platform. Please stay tuned for more updates in the coming weeks!
