Hello, x-code, you wrote: XC> What possibilities of your development environment the most pleasant and useful to you? 1. Illumination of some elements of syntax. Was specific I use illumination of keywords, comments, string and numerical literals. Basically it is any editor allows. But besides I love, when there is an illumination of some syntactic elements. For example in With ++ often write m_field that at code reading it was visible that this field, instead of local variable. It is very convenient, when IDE gives normal illumination of fields and such agreements lose meaning. 2. Quick search of errors without compilation is direct on an editing course. I remember, how earlier I on With ++ could write hour the code and then even minutes 15 to correct compilation errors. In the same Java an error shows at once and time is strongly saved. 3. Clever autocompletion. Allows not to read frequently the documentation, and to push Control+Space and to find the necessary method on a title, especially if approximately you remember that it is necessary for you. 4. The context-sensitive documentation. Javadoc, names of parameters, types and . In general everything that it is possible to define automatically in the given context and that can be useful for the developer. 5. Code static analysis. As a whole it is not critical, but it is convenient, when IDE highlights typical errors and allows to correct them quickly. 6. Automatic refactoring. First of all renaming. Remaining refactorings not so are critical, but too it is pleasant, when they are. XC> what possibilities you would like to see in your development environment? That is what possibilities you does not suffice? XC> for certain after all happens so - something you do and you think "and here it is good if there was such feature, it would be possible to simplify considerably operation, and it is not present and is not foreseen". As a whole all suffices. It would be desirable possibilities of change of the code in runtime, the more, the better, but it probably not to IDE a question.
