Topics are now compressed - it reduced TheIDE size, even with its small included help, by 256KB.
To convert existing topics, either touch them (Topic++ will always save using new compressed format) or if you have a lot of them, compile TheIDE in debug mode and convert them group by group - set the first topic in the group and invoke "hidden" Compress function from the file men (it just goes through the list, touching&saving files).
