There is no such place. Our development depends largely on user wishes and problems that users have. We also have some points we want to add on our own roadmap, but with all these unplannable issues it is not possible to make a "big" plan ahead. For server just some points already added for next release:
* Required for all functions of Repetier-Server Monitor 1.1.
* Improved rendering detection of width, layer height and object region.
* Touchscreen usability improved.
* Web actions added to e.g. control plugs with IFTTT.
* Shutdown after print button and event.
* Added DFU and DfuSe uploader.
* Password authentication for printer with TCP/IP connection using RepRapFirmware.
* Filament change disabled during print.
* Predefined temperatures for heated chamber.
* Improved replay list for rescue print.
* Improved security.
* Import of ZIP files to projects improved.
* Pauses are subtracted from printing time.
* Allow user icons for own commands.
* Fixed rescue system on non repetier-firmware systems not heating.
* Fixed permission required for timelapse setting.
* Fixed temperature parsing for Alfawise printers.
* Fix webcam rotation in print reports.
* Fixed problem adding new extruder.
* Fixed some styling issues.
If you have a problem that others might also have and seems not covered, please let us know and we might add a solution to it or can name one if it already exists.
