Trying new IDE: I cannot make Dexed work

[Eric P626]

I was currently using Code::Blocks since I used to code in C. But 
I realized that there is limited D language support in this IDE. 
There is no code completion and refactoring variable names does 
not work for example. I can still manage to compile and run the 
program with ldc.

In order to find a new alternative on linux, I was checking the 
list of IDE found here:

https://wiki.dlang.org/IDEs

I did not want to use IntelliJ because it's fat, slow and memory 
hungry. The interface is also overcrowded.

I did not want to use VScode because ... it's Microsoft. Still, I 
am willing to use it as a last resort option.

Dexed was one of the available options. So I installed the 
software and managed to run it. Now I tried just to create a DUB 
project add a file to it and compile and run.

* I cannot add source files to projects
* Even if I selected LDC as the default compiler and specified 
its path, it still try uses DMD to compile code.
* Variable renaming does not work, nothing happens.

So I was beginning to wonder if Dexed was actually a solid IDE or 
it's just me that does not understand how to use it.

Else, I wondered if I could try a generic IDE like Geany and try 
to configure the compilation process manually. Still, not sure I 
would be getting advanced feature like code completion.

Anybody familiar with dexed?

Else, should I stick to Code::Blocks or switch to something else?
