+###### Notable features {#notable_features}
+
+` * :!: It is possible to use potentials calculated for a certain geometry as a starting point for a calculation with modified geometry.`\
+` * You can change the angular momentum cut-off parameter lmax (LMAXD in global.conf) without having to create a new starting potential and shapefun file.`\
+` * You can set target_rms in input.conf and the calculation terminates when the desired rms-error is reached.`\
+` * No recompilation is necessary when changing input parameters`\
+` * Shape functions do not have to be calculated by separate program`\
+` * Shape functions for other codes can be generated by setting 'write_shapes = 1' in input.conf`\
+` * Several checks to ensure consistency of input and during calculation`\
+` * Error messages`
