Here's another important steem tool steemyy developed by @justyy. Some of the steem tools perform the same operations but it seems some tools are better suited for a particular operation. Well, it's all based on your convenience though.
Steemyy actually performs myriad operations, one post wouldn't be able to cover it all. Here is a brief summary of some actions steemyy offers.
Account services/Essentials
Just like steemworld, steemyy also gives an overview of your account. Your steem power, voting mana, wallet balances, basically all there is to know about your account.
keys recovery
It could also be used to retrieve other keys using the master key i.e you can obtain your posting or active keys once you have your master password (Never misplace your master key, doing so invariably means losing access to your account). Also, you don't have to worry about key safety on this platform as data only stays locally in your browser.
Witness tools
you can actively take participation in voting witnesses you feel are adding value to the ecosystem using the witness voting tool. The steem witness ranking tool also allows one to view the current witness rankings, more like a leader/score board.
From the screenshot, it's evident that steemyy tools also extend to delegations and delegatees, upvotes and some other miscellaneous tools as stated below.
Steemyy offers a lot of important tools, and new tools get added to the platform at intervals. It's very advisable to review the tool and gain some user experience as it has a lot more to offer than my review could cover.
