Money Button's UTXO Splitter
I'm not sure if the problem of 25 unconfirmed transactions still exists -- if it does, this tool by Money Button can help (MB users) to continue transacting. 😉 In other, better, words: "This tool allows you to split your balance evenly into any number of UTXOs. First you need to select the number of UTXOs, and then swipe the button."
