I've been trying out PSPad and it mostly looks good although it has been difficult to switch from UEdit. Because I am so used to UEdit, it is hard to remember how to do things in PSPad (this, of course, it not a fault of PSPad).
Although PSPad has a PRG definition file, it is for Harbour. I had to create my own for FW but I have been unable to figure out how to configure it for Class syntax and this is a show stopper for me since I do almost everything using Class syntax. Uwe, have you been able to get Class syntax working? By this I mean getting it to work in the "Code Explorer" panel.
Another thing I miss from UEdit is that there are no user defined buttons on the toolbar. I used this a lot in UEdit.
I use UE Studio and find it works quite well. I have the most recent version, its quite affordable, and the user defined buttons help me with performing quick builds with different compilers.
I do need to clean up my initialization file for formatting, but otherwise, it works fine.
I keep up with Multi-Edit, but it has been years since they were able to put together an update. They acknowledge staff issues so who knows if they will ever release a more current update.
