I noticed that by default, hard line breaking is activated. This makes an email harder to read espacially on low-resolution-screens such as cell phones, while on big screens, there will be a huge empty space in the thight corner of the window, which is not appropriate. Do you know what I mean? It took some time to find out how to disable it. Finally, I made it, but what's the use of it? Maybe there are some who swear on it, but I guess for 90 percent of all users this is just annoying feature. Reproducible: Always Steps to Reproduce: 1. Do a fresh Installation of Kmail 2. Create a new Mail and write some text. Actual Results: You will see that by default Kmail does a hard line break before the window ends. Expected Results: The text should fill out the hole window and adapt itself dynamically to its size just directly after the Installation. Also, in the Options menu (of the composer?), you will find "Line Breaking" enabled by default. This is an unnecesscary handicap. It is easy to disable, but it is annoying.
This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present? If noone confirms this bug for a Framework-based version of kmail2 (version 5.0 or later, as part of KDE Applications 15.12 or later), it gets closed in about three months.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
