SMSdroid is a light and fast app for reading and sending text messages. It is optimized to play well with any app capable of sending messages. A good example is WebSMS.
I've added a feature to select and bulk-delete many threads or conversations (as opposed to deleting only one specific conversation or all SMSes on the device, which was already implemented).
There is a hard-coded pause of 40 s after each conversation deletion, in order to avoid deletion exceptions in the case of there being too many messages and not enough phone resources to deal with in and delete conversations properly.
I have no intention on tackling the issues or TODOs I've added to the code in the near future and probably ever.
